CZ-75B converting to single action?

[1911Luvr]

I was unable to find any threads on how to convert a CZ-75B to single action, so has anyone done it or know how? I would like to add the flat trigger from the CZ-75SA Tactical Sport too. What parts do I need to replace, omit, etc.?

The curved trigger kills my finger after a couple mags, and I am used to carry cocked and locked like my 1911s so I don't need double action. Also, once it is changed to single action, is it still approved for IPSC production class?

Thanks!

Pretty easy to do.

Swap the hammer, remove disconnector, replace trigger.

Not sure abotu IPSC, but USPSA and IDPA it would not be legal for production/SSP

For IPSC, the gun would become a Standard Pistol handgun and you'll end up competing against major caliber pistols. In IPSC, 15 rounds are allowed in the Standard pistol division. In the US, the gun would become a Limited gun and it will also be competing against major calibers.

LOL, A fellow USPSA shooter is actually going to put a shadow slide and convert my 75SA to double action with the CZ85 combat trigger, so I can use it as a backup to my SP-01 for matches...not that I think I'd ever really need a backup gun for the intermittent local club matches that I shoot. But it would also give me an alternate gun just for fun. And putting in the flat trigger and removing the disconnector will put it back into SA mode. Actually pretty pointless except for the gun of experimentation.


You can shoot the SA gun in Limited 10. If you have higher cap magazines, it might make sense to shoot it in Limited so that you can at least get the advantage of the higher capacity vs the major scoring. If you go L-10 then it's just your minor+speed vs their major scoring. (NOTE: I just saw a scoresheet where the L-10 winner was shooting a Glock 34 (9mm) and he beat out the guys shooting major, based on both speed and accuracy, so it IS a viable choice)

Not difficult. My SP-01 is now single action only with the dual adjustable (set screw adjusts for pre- and over-travel) trigger:




+1 to what zfields said, although I'm not even sure you have to replace the hammer. Yeah, I could look it up but I'm too lazy. Remove disconnector for sure, and put in new trigger for sure, not sure if hammer is a necessity.

Also, I would highly recommend a new floating trigger pin from Cajun Gun Works. Often the factory ones are not reusable due to being "retained" by smushing one end. http://www.cajungunworks.com/spring_kits.html

David at CGW can also set you up with all of the other parts you might need to switch to Single Action and have an absolutely amazing trigger, including the trigger itself and maybe one of his race hammers. My gun, pictured above, actually just shipped to him today to have him put a race hammer in it and just generally tune this thing so it's as good as a CZ trigger can possibly be. Meaning: absolute minimum of pre- and over-travel while still functioning reliably and the shortest possible pull and reset distances with a crisp, clean break. It is my preference to keep the trigger a little heavier than some might for target/competition shooting, and he's aiming for 3.5 lbs or maybe just a teeny tiny bit over that. The thing is going to be AWESOME when it comes back and I expect it to be as good as my Springfield Professional, which is one of the best anywhere hands down. It's already close, and after David's done with it I think anybody who spent $3,000 or more for their 1911 is going to be pissed when they feel how amazing this thing is

Probally don't need to swap the hammer, but if you're going to go SAO, might as well make it a nice trigger and kill the camming!

[JeremyS]

BTW it's a common modification to reduce the curvature of the DA/SA trigger that's in your gun. People will heat it up, put it on a hard, flat surface (anvil top of a bench vice being basically ideal), then tap it with a hammer to flatten out the curve. You can get away with quite a bit of this before the trigger becomes too long for the trigger guard, and it makes it much more comfortable for a lot of people -- I'm confident you'd be in that "a lot of people" group considering what you said in the original post.

I will give CGW a look. I'm curious to feel how crisp and light they can make a CZ trigger, but I have a couple $3000+ 1911 customs and I am highly doubtful the trigger feel of any other non-1911 pistol could be better. I try to keep an open mind, but I have never felt anything as good as a properly tuned 1911 trigger.

BTW, that is a very good looking pistol!

[JeremyS]

I don't know about better -- it's so subjective and all -- but it can be pretty freaking amazing. I don't think you can get the total travel to be as short as a 1911 due to mechanical differences, especially reset distance, but it's not too far off and I personally don't find that as important as an awesomely crisp break, which you will get. Total movement from all the way forward to pinned at the back is super short, but not as short as you can get a 1911. I think the reset on the CZ is typically louder and more tactile though. I'm not sure if it's distance to the trigger or angle to the trigger or just the amount of rounds I've put through it compared to my 1911's or what, but the CZ trigger is more comfortable and natural for me.

If you want another $3,000+ custom 1911, I'm selling my Professional

I don't have my CZ set up that way, but I got a chance to shoot a buddy's 85B combat that had been tuned, and oh good Lord that trigger was sweet. You might be surprised.

If you convert to SA ( I have done several), there are a few other gains you can make.

Trim, modify or eliminate the firing pin blocker actuation lever, this destroys the ability to have a short trigger rest.

Stone the triggerbow sides and other internal trigger parts since you have them removed.

You can swap out hammers, or cut the hooks on the hammer.

Swapping parts is half of it, that gives you the ability to make adjustments which is where most of the gains are.

Yes sir, a CZ most definitely can. And I have been working on 1911's for 30+ years. As a matter of fact, I have a drop-in hammer kit that will probably amaze you.

[asgalindez]

Sent one of my 75B SAs to CZCustoms. Competition hammer, SAO straight trigger, Remove FPB, adjust pre- and over-travel equaled a 2.5lb trigger pull that would rival a custom tuned 1911. Anyone that's tried it out has been thoroughly impressed.

I've heard the CGW stuff is equally impressive.

Hey Schmeky! Glad to see you over here on calguns!

I still would like to send my 97b over to you for some treatment...I love the shortened frame look and would also like you to do a few other things. I shot you a PM a few days ago on the CZ forum, please respond when you have a chance. Thanks!

[schmeky]

SDRider858,

Man I love those 97's. Be glad to help you out. I like it when customers call me and say, "Hey, you sent me the wrong gun". True story, customer was surprised with his "new" CZ
