I have a new CZ75B and I’m looking at upgrades. I purchased a set of grips from LOK and they are on the way. I was looking at the Armory Craft website and saw a flat trigger that is SAO. Not sure how this works so I am looking for info. Is the flat trigger less pull and take up? Anyone with experience with Armory Craft?
 
Any of the flat SA triggers provide a pretravel and overtravel screw. So you can tune the trigger travel to it's shortest possible length. They will, of course, eliminate the DoubleAction mode of the trigger.

For a CZ75B, you have a firing pin block, so that will dictate some trigger movement to allow it to work. The CZ Shadows/Chechmates/Tactical Sports have no FPB, so can be tuned a little shorter. Although, a short reset kit can be had from CZ Custom and CGW that will allow the FPB to function and shorten the reset some on a FPB pistol.

Armory Craft is selling the Euro CZub products. They are good quality and work well.

IMO, the SA only conversion is good for range guns and competition guns, but personally I wouldn't use it for a carry gun.
 
For the very lightest and shortest pull, you would want a race hammer and sear, the SA trigger, and remove the FPB.

I did the flat trigger, adjustable sear, and race hammer upgrade from CGW. Bought the stuff in BST here though. That combo is near insane in how light the trigger is. Mine is a carry gun so I also added an over powered hammer spring to mine to bring some wight back into the trigger pull.

This is no joke. ^^^ Keep in mind that if you leave the FPB in you can pretty much only adjust over travel. How much the trigger moves after the gun fires. You can take that to near zero, which is really nice. If you adjust the pre travel with the FPB in you will disable the FPB and the hammer will drop but the gun will not fire. There has to be enough movement in the system to allow the FPB to move out of the way. And with no pre travel it does not have a chance to get out of the way. Since mine is not a carry gun, I did not want to do that.

Dude, you are in Hickory. Take a trip over here to Longview and see for yourself. I'd be more than happy to let you dry fire it a bit. If we can get schedules worked out we could take it to the range.

Good information guys. I had to read thru each of the post a couple times to get a better understanding due to my limited understanding of the mechanics in a CZ. @chiefjason I’m going to take you up on the meet up but it’s going to be a couple weeks due to work and a family vacation next week.

My next question for you guys is if I use the gun as a carry or truck gun will the elimination of the DA make this gun unsafe? Or is this making it like a striker fire with a thumb safety? What do you guys think the percentage of pre travel decrease is with a SAO flat trigger?
 
IMO,
If it were a truck gun type deal I’d leave it DA/SA and have it hammer down with round in chamber in a good holster. I just feel that’s more appropriate condition for that use.

I would then work on smoothing out the action so that the takeup was smooth and useable.

I only use a cocked and locked CZ in a competition holster, and it is only loaded prior to shooting it at the range. It is never loaded, and no magazines are loaded, at my house or in my vehicle. None of the CZs I have owned had firing pin blocks. So they are competition guns only.

Just let me know. I carry mine a lot, and carry it cocked and locked. You are not making it striker fired with safety, you are making it a 1911 or Browning Hi Power basically. If I considered it unsafe in Condition one I would not carry it. I don't consider it unsafe and I do carry it like that.

It may have taken out a slight amount of pre travel, but not much. Like I said earlier, the FPB gets in the way of removing much. What it does is lighten and smooth up the trigger break. So as soon as you start to put pressure on the trigger after take up it fires. BTW, over travel is very important to and that is near zero with the flat trigger. One other thing is the reset is so fast it's almost unnerving. I only thought I knew how to dump a mag before. You have to feel it to believe it really. If you twitch the trigger resets.

If you are wanting a truck gun, there is absolutely nothing wrong with the CZ's DA mode. And to be honest, I went SAO because I wanted to and carried condition one anyway. I shot the CZ pretty much equal in DA or SA. My experience was that SA had a lighter trigger pull, but more creep and some over travel without work. While the DA had no creep, just a nice smooth pull against the hammer. Personally, the creep gets me most times. Too much creep and I want to roll my wrist which gives me low left hits. A good DA trigger and I still shoot it well because mentally I have something to feel as I pull. That soft, mushy, nothing from creep bugs me. Which is the main downside of the SAO conversion if you leave in the FPB. The creep/take is still there to an extent. What evens that out is how dang smooth and light the trigger becomes. Instead of nothing into a significant pull it's more like nothing into a slight resistance and fire. Which does help.

BTW, Foothills pawn and gun had a SAO CZ75b a while back unless Dave has it now.

For a carry or truck gun I'd either go CGW Defensive package or just leave it stock and shoot the snot out of it. And dry fire the snot out of it. I used to have a stock PCR that was fairly rough in the trigger department when it was new. I dry fired it a ton and after putting a bunch of round through it things smoothed out nicely. It was anything like a custom trigger job, but it worked well.
