    Mine was the most accurate handgun I ever fired. What is "camming"? Live with what?

    I'm assuming he means that just before the hammer is released it moves a fraction of an inch back. Guessing that it was designed that way as a supossed safety feature. Never liked it when I owned a CZ.

    Hammer camming can be released easyly by adapting an Angus / CZ competetion hammer to your CZ.
    Also a potent gunsmith may alter the sear and hammer engaging angles to decrease the amount of camming.
    But if it is a carry pistol, than let it stay in that way for an additional safety feature under stress.

    The hammer camming doesn't bother me at all on my P-01. I actually shoot the P-01 better than any other pistol I own, including a 1911.

    what did you replace the cz with?

    DirksterG30:
    Are P-01 sights similar to 75B sights?

    Hammer Camming

    Hammer camming is actually intentional and necessary. Try going the opposite way (let off as I call it), and see what happens. :eek: Been there done that

    Reducing it can improve the trigger. You still want a little hammer camming though.

    I had not heard this before, so I got out my PCR compact, unloaded it and dryfired it. It has always had a lot of "creep" in the SA pull. Sure enough, the hammer moves back a little as I start the pull. This must be accounting for the "creep," as the hammer stops moving when the actual trigger "break" point is reached. I've had no accuracy problems with it, however. I am now leaning away from having the trigger job done, even though I live near Angus Hobdell:cool:, actually meeting him once for some grips.

    This is one of the things I disllike about the CZ platform. It does interfer with accuracy. It reminds me of shooting a DA revolver, but not nearly as long of a pull. The AR-24 did away with most of this.

    While I find the long cammng a problem, I do realize the CZ platform is an accurate handgun once one becomes accustomed to the trigger pull.

    If the roughness could be taken out of the hammer camming, I could live with that, without the expense of new parts (which might not be available for my gun anyway).

    Does the single-action version also have hammer camming?

    The correct terms for this discussion are....

    Negative Engagement - As the trigger is slowly pulled, the hammer moves forwards slightly before breaking and contacting the firing pin.
    This is also known as a "hair trigger" and is DANGEROUS!

    Neutral Engagement - As the trigger is slowly pulled, the hammer remains neutral and does not move before breaking and contacting the firing pin.
    Not considered the best idea, but okay for range-only toys.

    Positive Engagement - As the trigger is slowly pulled, the hammer moves rearward slightly before breaking and contacting the firing pin.
    This is the safest type of hammer/sear engagement and prefereable for regular firearms.

    Some CZ pistols have a fairly steep positive engagement. This is extremely safe, but some find it annoying as you have to overcome the additional resistance before the trigger "breaks" and the gun goes off. If your positive engagement is too steep/strong, take it to a gunsmith.

    SOME POSITIVE ENGAGEMENT IS GOOD. DO NOT MESS WITH THE SEAR ENGAGEMENT UNLESS YOU HAVE REAL KNOWLEDGE AND EXPERIENCE WORKING WITH TRIGGERS. A TINY ERROR WHILE GUNSMITHING HERE WILL CREATE A LETHALLY DANGEROUS FIREARM THAT COULD GO OFF AT ANY TIME WITHOUT WARNING!

    Both of my 75Bs had that issue. Bit of work with a stone and its just noticable to the eye and you cant feel it now.

    Well

    It has nothing to do with the CZ platform. Other guns have it too. It's simply the angles on the sear and hammer hooks. Most likely, CZ is playing it safe in regards to lawsuits. The older CZs seem to have less angle on the sear/hammer, and thus less camming (and usually better triggers).

    The problem with going for neutral engagement, is that after a little wear, neutral becomes let off.

    With a short trigger shelf and bad angles, you'll have a gun that'll fire when you drop the slide and or fire multiple shots per trigger pull. Been there done that.

    A hair trigger is just a light trigger.

    If CZ uses it, it has to do with CZ. That doesn't mean it is exclusively CZ, but rather inclusive.

    Don't argue in absolutes. There are degrees. CZ doesn't need to have a neurtal engagement, but doesn't need to have the extreme positive either.

    There is ann informative "trigger job" on CZForum.com. It has step-by-step pics and instructions. These include changing the angle on the sear to reduce camming.
    I did My 75B - springs & trigger job) and the improvements were amazing. I didn't try to change that thin angle, just smoothed the rough surfaces. The camming became a total non-issue.
    The camming on the CZ75 is difficult to work because the surface is VERY thin. Imagine the sharpened portion of a wood chisel only 1/16" (+/-) thick and changing that to a shallower angle precisely by hand.
    The Angus Hobdell competition hammer and trigger job fixes the problems.

    What?

    Huh?? You say not to use "absolutes" and then turn around and use them yourself. Reread what I wrote.

    You missed my point. CZ doesn't do it because the "CZ platform" requires it. They do it for legal reasons. It's a lawyer trigger.
