TOZ-35M Trigger problem

Found time to test my new TOZ-35M. Live shooting (amazing +15C outdoor temperature in the end of December).

First of all - I had to invest time to properly fit my grip for new pistol (every TOZ frame is unique +/- 1-2mm is normal).

First shot - 40cm too low. I lowered the front sight with a file (2mm) instead of making 40 clicks. So I have "clicks"-reserve in both directions now (low/high).

Trigger was awful - random trigger character. Very long, short, short, very long again... unpredictable. Solution - fix middle lever (part #23) with a file. See picture below.

Fix middle lever (part# 23)

Second TOZ-35 in my collection

This TOZ-35M I bought last Saturday for 111,60 Euros. Perfect condition (Serial Number 862###). The year 1986??? With Morini grip (a little bit modificated). All tools and wooden case (with key) are like new.

The pistol was very dirty... A lot of grease.

Washing with hot soapy water.

All parts are cleaned and wiped with WD-40.

Please stay calm. It is only translation. It is not excluded that interviewer did a couple of mistakes. Historical inaccuracies are not excluded. Leave your comment if you find any inaccuracy.

Buryat Father Of Russian Arms
Efim Khaidurov

1955 - 1963: member of the Soviet national team; has won multiple World, European and Soviet Championships in a variety of pistol disciplines.

1967 - 1976: head pistol coach of the Soviet national team; personal coach of World Champions Stoliarova Nina (1970 Phoenix USA, 1974 Thun Switzerland), Suleimanov Renat (1970 Phoenix USA) and many others shooters. The Soviel team led by Khaidurov has won 12 gold medals of 14 possible at the World Championships in Thun Switzerland.

Almost all World Championships since 1962 and Olympic Games since 1976 were won in different disciplines with pistols designed by Khaidurov (some of the arms were personally made by Khaidurov).

1976 - 1984: head of sport shooting department in State Central Institute of Physical Culture.

Contributed to the improvement of the rules of international shooting competitions; has achieved inclusion of air pistol discipline in the Olympic program. All this is done by one person - Efim Khaidurov.

How did you get started? You first experience with the arms? 
In the Ust-Orda Buryat Autonomous Okrug (District), where I was born and where I spent my childhood, almost every man hunts. I went hunting with my father but I did not shoot. I was used as a beater. For many years, had not thought that the arms will be the main thing in my life.

Your adolescence fell on the years of the war ...

Right from the beginning of the war, as many of my contemporaries, I wanted to theater of war. But the enlistment office did not accept my earnest desire. As a child, I was diagnosed with a heart defect. Besides, I looked younger than my age and I was short.


In 1942, I graduated from high school and I sent an application to the Moscow Aviation Institute. I was called for the entrance exams, but my father did not let me go. He told me that now it is necessary to defend the homeland. I worked for more than one year at an aircraft factory in Ulan-Ude. Having mastered the machines I worked as locksmith and milling machine operator. In 1943, I went to study at the military school. Very soon I was promoted to an officer and as high achiever was sent to the Ministry of Defense. In 1948, I was discharged.
I became interested in the theory of shooting, read a lot of books. In school, we were taken to the shooting range. We had four classes and I learned to shoot with a small-caliber Nagant revolver 42-43 points at 25 meters.

So, after demobilization in 1948, you went to the shooting sports?

I went to sports - in athletics (pole vault, decathlon). At the same time I worked as head of educational and sports department of the city council of "Dynamo" in Ulan-Ude. One day my friend offered to take part at the shooting competition. I trained one month with his TT pistol and I spent 300 rounds of ammunition. As a result, I earned First-Class Sportsman (Sports Classification System of the USSR; equates to regional champion).


In 1950, I was seconded to study in Moscow - special courses in the State Central Institute of Physical Culture. And in 1951, I was enrolled in the Mechanical Institute, which was reorganized in 1953, and I was transferred to the Bauman Moscow State Technical University (Mechanical Engineering Faculty). Then at age 28 I started shooting sports training.

Who was your coach? What was your first success in the shooting?

The greatest influence on my formation had Zhgutov Oleg, Merited Master and Coach of Sport of the USSR (equates to international champion who has made valuable contributions to the sport). He was head of the sports department of the Institute and coached shooters. In 1954, I joined a team of Moscow's DOSAAF (Volunteer Society for Cooperation with the Army, Aviation, and Fleet). In 1955, I took the second place in free pistol and center fire pistol at the USSR Championship and I was selected for the USSR national team.

Did shooting affect your performance in the University?

Because of the long trips to the competitions and participation in training camps I had to take a sabbatical, but I studied well. I graduated in 1958. I defended my thesis in 1959.

Do not confuse the date? As far as I know, since the beginning of 60's soviet shooting team already used your pistols?

No, I do not confuse the date. Our shooters always were understanding technical details of firearms better than their foreign counterparts - not out of choice but out of necessity. Domestic firearms factories, compared with foreign companies, have never satisfied design requirements of leading shooters. In the West everything is predefined: some people shoot, while others produce and repair. At the beginning of my career Soviet shooters hadn't have quality sporting arms, although coaches and athletes were high qualified.
In the 1954 for the first time our team took part in the World Championship and immediately before the competition we had seen that we have nothing to do here with our "Nagant" revolvers. The officials of our team had taken an unprecedented decision and bought directly during the championship two new "Smith & Wesson" revolvers. Our boys won the team championship and set a new team world record.
Personally for the first time I used MTs-2 free pistol and constantly worked on its construction trying to satisfy my personal needs. In the 1957 I set a goal myself - to design new free pistol.

Based on MTs-2 or foreign free pistol?

I tried to completely abstract from well-known to me models, because its demerits could be preserved in the new product. All parts for the first prototype, except for a few standard screws, I had made myself. This pistol has become my thesis work, although my specialization in the institute was completely different - the technologist. For thesis defense I had prepared three prototypes of free pistol made by me in the workshops of the Bauman Moscow State Technical University. To study the "balance" some gun parts and components were made of duralumin, and one prototype was completely made of steel.

And which one was the best?

Of course one made of steel. Our Soviet famous shooter Kreheli risked and he was shot with it at the Championship of the Soviet Union in the 1959 and won. It was before my thesis defense. Already in 1960s some newspapers have published articles mentioning Khaidurov as designer. The first prototype was called the X-1-MT "Baumanets". Later I made only one change in its construction. Also in the 1959 the national team had tested the pistol. It was approved and I got only one comment concerning the trigger. I modified it - made the intermediate arm bent for an even smoother trigger.


In the modern pistols the trigger smoothness provided by electronics.

Athlete should always have a choice between electronic and mechanical triggers (but smooth mechanical trigger). Electronics still makes the gun more expensive and susceptible to external influences. Electronic trigger was used for the first time in the pistol of one American, who became the medal-winner at the World Championship (1954 Caracas?), but that new product didn't become popular. The Hämmerli company after many unsuccessful attempts to make a smooth mechanical trigger started to use electronics in the early 1970s.

The paradoxical situation: the student makes a single product, the quality is better than the state industry!

Not exactly. Many foreign companies produce single-peace firearms for the Champions. However, the same companies provide full service-support on the first demand of the client. Our best shooters always had dreamed of it. Unlike typical designer I used my pistols myself, I experimented with pistols and improved construction. I worked directly with the national team and asked for their opinion - not all designers have such opportunity. At the long last - I have good education.
I had also met many talented engineers, but heads of departments were people, who didn't have an idea what shooting sport is (delegated by Communist Party).

Many heads of departments showed absolute ignorance in the design requirements. They were also top-level professionals in intrigues. So when we had started to prepare my first match pistol for the production I supposed to name it TX-62 (the place and year of manufacture - Тула Хайдуров / Tula Khaidurov), but the deputy chief designer insisted on "TOZ-35 (designed by Khaidurov)". But then, my name was listed only in the data sheet of the first series. Some of the factory bosses did not believe that man alone is able to design a normal firearm. They really advised to me to do something easier (improve wooden box for spare parts for example).

Glory, prestige - OK. Is clear. What about material stimulation?

There was a simple formula for calculating the financial reward: A = 20 rubles × K1 × K2 × K3 × K4. "K" coefficients were set depending on how friendly engineer with management. As a result, bonus could be 20 or 20,000 rubles (1960-1970). One big boss thought a long time about the amount of the bonus for "TOZ-35". I said I cannot buy me a car. He asked: "And how much is Moskvitch? 3500 rubles? OK. 3500 rubles". But I didn't buy a car. I needed money for my family and children.

For IZH-KhR-30 and IZH-KhR-31 (very successful models) we both - I and my partner Razorenov - were rewarded with 2,800 rubles. For TOZ-36 revolver I have not got a penny. Design of firearms was considered to be a hobby of mine, and I was paid as a coach. Most of the time I worked with national team as gunsmith.

In many photos of the period when you were in the USSR team, you were wearing glasses. Are glasses a problem for shooting?

It is a wrong belief that the shooter must have perfect visual perception. I remember one of the best shooters in USSR team - Kalinichenko - he was wearing correction glasses (-D 4.5) and he won the World Championship in 1954 (Caracas). The main thing - proper correction glasses.

Is it necessary to cover the other eye during aiming?

Personally, I believe that if a shooter wants to cover other eye, then the narrow cover strip must be used (to cover firearm only). Large cover strip affects stiffness and coordination. General question - light circumstances - a big problem. At open shooting ranges eye iris is about 1.5 mm, at indoor shooting ranges - about 6-7 mm. Scores are getting lower if shooter switches to indoor shooting range after open shooting range.

Was it difficult to combine the design work with the coaching?

Until 1967 I combined three things - I was firearms designer, coach and shooter and until 1963 I was in USSR team. All liked all three occupations, and one became a continuation of the other. The main problem - lack of time. And because of that I am one of the few shooters, who are not engaged in hunting.

My coaching principle - a strict individual approach to an athlete (look at problems from the same point of view; use the same vocabulary as athlete...).

Did any foreign company invite You to work abroad?

"Feinwerkbau" invited me in the 1969 and in the 1975. It was impossible to accept such invitation in those years. "Walther" invited me in the 1993-1994.

What is the salary offered? And why you did not accepted the invitation?

They offered 300 DM for one day of consultations. I had a doubt: Well, I'll work on them one month disclosing all the details (and why else would they need me?). And then goodbye. But the main reason for denial was that then our team had to buy abroad and import firearms with my inventions. Our opponents would get an advantage. This is unacceptable for me. I have always considered myself as a patriot.

Pardini SP Trigger Adjustment - Solution

My problems with Pardini's trigger I described earlier.

By the way - TargetTalk's member Gwhite offered wonderful trigger adjustment diagrams (must have!). And don't forget this - Don Nygord's instructions.

Also. I have adjusted the trigger settings once again and I have made it shorter (see my first article with the picture).
Next two training sessions I tested new settings. About 40 five shots series (rapid fire pistol). 2 or 3 times I could not properly reset the trigger. Huge progress. But... scores. Something was wrong. This year I didn't have training scores below 278-280 as I remember (half program); Usual training score - 282 - 287. Highest was 289. And this time I did only 260 (first attempt) and 267 (second attempt). It is impossible to lose 20 points within one week (or 40 points - full program). Everything was the same except new trigger assembly. The same feelings. But different scores. 43-45 in eight (!!!) seconds series instead of usual 49-50. "Eight" at three o'lock, "eight" at 6 o'clock and so on...

The problem was localized and solution was found.

The second stage was too long.
The solution: Screw out the 2nd stage engagement screw "CS" till you don't have 2nd stage. Cock the pistol (unloaded!). Now - as Don Nygord says - Turn "CS" in clockwise until you feel the "2nd stage" appear about at the end of the pull. But do it in very small portions (about 1/32 turn) and after every turn try if "2nd stage" "appeared". If yes - you are done. 2nd stage must be very very very short (in my case). As electronic trigger.

Next training session I begun with 49 49 50 49... everything was fine again.

.22 Long Rifle cartridge height

I have a lot of troubles with GECO Pistol .22 lr at the moment (ordered and bought this spring).
Lot number is "2GN428".
Sometimes Pardini's magazine won't feed next cartridge. Cartridge stuck; won't move upwards.
I have collected such "trouble-makers" and measured them with digital caliper.
Cartridge height varies from 25,03 to 25,21 mm (15 cartridges tested).

For comparison:
GECO Pistol .22 lr bought in 2012: from 24,89 to 25,01 mm (30 cartridges randomly tested).
RWS Pistol Match: from 24,50 to 24,56 mm (random test).
TEMP Pistol (made in USSR in 1991): from 24,86 to 24,91 mm (random test).

By the way; according to Wikipedia .22 lr cartridge standard height is 25,40 mm (exactly 1 inch). 

Verdict: must be used only for training.

Pardini SP Trigger Adjustment

OK. It is not so easy as I imagined.

For two days I switched to mechanical trigger and after all I adjusted the trigger as I like (I thought so). Today during routine rapid fire training (the first training with new trigger) I could do only 3 or 4 "normal" series (of 18). "Normal" - I mean - I could reset the trigger five times (and five bullets left the barrel in time). I was totally disappointed. After every shot I had to move my finger back too far to reset the trigger (I think I had to completely release the trigger). Only then trigger bar / dis-connector took appropriate position. Never had such troubles with Feinwerkbau AW93 (as well as with Pardini SP1 electronic).

Don't forget - I am talking about rapid fire (8, 6 and 4 seconds).

Now, at home, I think I found the solution. Overall trigger pull (1st and 2nd stages) must be as short as possible (and save - of course). Maximum 0,75-1,00 mm first stage length (movement of the trigger shoe). Very short and crisp 2nd stage.

Following photo fully describes my solution.
Pull the trigger and hold. Cock the hammer (pull the slide backwards and let it glide forward).
What do you see is very short overlap between the trigger bar / dis-connector and sear ("corner to corner").
And today I tried to shoot with 1,5-2,00 mm overlap.  Huge difference. 2,5 mm finger's backwards movement to reset the trigger was too much for me. I will let you know If this solution works (at least for me).

Switched to Pardini mechanical trigger

Local Pardini dealer quickly sent me the new frame. Switched in 5 minutes.
I am experimenting with six trigger setting screws at the moment.
Total costs: about 450 Euros (but reliability is very important and it can cost more sometimes).

Most beautiful MTs 55 ever

Little Serbian tragedy (ECH 2013 Free Pistol Men)

European Shooting Championship in Osijek.

Free Pistol Men.

MIKEC Damir. 54th shot was "3". The Shooter or team-mate protested the indicated value (ISSF Rule 6.10.7).
End of the competition. First preliminary results - Damir is among eight best shooters qualified for the final round (last series is 84). Serbian Team is on the third place (two points ahead of Russian Team).
Control target was examined: shot was scored correctly. Damir gets two points penalty and qualified 12th. Serbian Team is on the fourth place behind Russian Team (equal results but Russians have higher number of inner tens).

:-/

Pardini electronics failure

I did 1210 shots and couple of thousands dry fire clicks (approx. 8000) after replacement module was installed. Failed again. I think I will switch to mechanical trigger.
Today I used my backup pistol (Feinwerkbau AW93).

РАХИ САРНОБАТ из Индии заняла первое место на этапе Кубка Мира по стрельбе


РАХИ САРНОБАТ из Индии заняла первое место на этапе Кубка Мира по стрельбе (стандартный пистолет), опередив всех фавориток.

Для людей мирских это событие может пройти незамеченным, ну заняла и заняла, с кем не бывает. НО ! Дьявол, как известно, кроется в деталях. А детали они таковы:

1. До прошлых летних олимпийских игр у индусов не было ни одной золотой медали в стрельбе. Вообще попадание индуса на подиум в стрельбе воспринималось как нонсенс и, скорее, как ошибки соперников. А в женкой стрельбе - ну... примерно как падение метеорита на Челябинск. И тут, что называется вдруг...

2. Когда спортсмен выигрывает, я в первую очередь спрашиваю - КТО ТРЕНЕР ? А у тренера вполне типовая такая индусская фамилия, да и имя тоже и отчество, зовут его ПОДДУБНЫЙ АНАТОЛИЙ ПЕТРОВИЧ. И кто же это такой, товарищ Поддубный ? Именно товарищ, так как он Подполковник Советской Армии и в прошлом старший тренер сборной СССР по пулевой стрельбе, вырастивший не одно поколение чемпионов мира и олимпийских игр. Достаточно сказать, что рекорд Мелентьева (не побитый с 1980 года) это дело рук (и головы) Поддубного.

3. Но самое пристальное внимание в технических видах спорта, а в пулевой стрельбе особенно, приковано к инвентарю спортсмена, в данном случае к ПИСТОЛЕТУ, от которого в стрельбе зависит, конечно, не все, но очень многое. А пистолетик очень интересный. Это Feinwerkbau AW93. Не вдаваясь в историю про то, как российские спортивные чиновники передали (ну, разумеется, безвозмездно для государства, но возмездно для себя) фирме Feinwerkbau чертежи новейшего спортивного пистолета конструкции ЕФИМА ЛЕОНТЬЕВИЧА ХАЙДУРОВА, можно сказать, что это слегка ухудшенная копия (из за бестолковости некоторых немецких инженеров, которые выкинули в угоду технологичности пару деталей, так и не поняв их назначения) ХРБ-88.


Итак, что мы имеем. Имеем по факту СОВЕТСКИЙ ПИСТОЛЕТ и СОВЕТСКОГО ТРЕНЕРА. При этом сочетании, естественно, не уменьшая заслуг самого спортсмена, уже не важно, в чьих руках находится пистолет. ПЕРВЫХ ДВУХ ФАКТОРОВ ДОСТАТОЧНО.

Что же имеем мы в тех видах спорта, где что-то стреляет ?

1. В биатлоне имеем Пихлера, пардон, уже отъимели...

2. В стрельбе имеем ОДНУ МЕДАЛЬ ВО ВСЕХ ВИДАХ СТРЕЛЬБЫ на последних Олимпийских играх, бронзовую... Да и с Кубками мира не густо...

3. Мы не выпускаем ни одного спортивного пистолета, спортивной винтовки и спортивного патрона.

4. За 20 лет мы закрыли более 1000 тиров

5. Приняли закон (и 288 постановление к нему) де-факто убивший спортивную стрельбу как класс.

При этом весь мир пользуется услугами советских и российских тренеров, разработками советских и российских конструкторов и уже открыто смеется над нами.

КАК ИЗВЕСТНО, ЛУЧШИЙ СПОСОБ ДОКАЗАТЬ ДУРАКУ ЕГО НЕПРАВОТУ - ПРЕДОСТАВИТЬ ЕМУ СВОБОДУ ДЕЙСТВИЙ. ЭТОГО ДОСТАТОЧНО ИЛИ ПРОДОЛЖИМ ДАЛЬШЕ ?

Checkering tools

Dembart's checkering tools I have used (my first experience):
  1. Cutter 2-32 (spacing tool; 32 lines per inch)
  2. Cutter F1 (used for making the original layout or pattern and to deepen the rows after they are marked in with the spacing tools)
  3. Cutter B-2 (a narrow bordering tool which is used to put the final boarder around the layout or pattern)
  4. Special S-1 Tool (as F-1 but for narrow places)

This tool for stippling I prepared myself with a file (usual M8 screw).
