    I bought a CZ97b right before the holidays. Have shot it a few times, and I'm not too thrilled about the stock trigger. Anyone upgraded their CZ97b with CGW parts? Looking at their Double Action Ultra-Lite Kit. I upgraded some springs on my Canik S-120 and it made all the difference in the world.

    I also have a 97B that I'm breaking in and have been researching and eyeing the CGW and CZ Custom offerings for them. Reviews indicate that the products offered by both of these groups perform as claimed, and pretty much everyone seems happy (or thrilled) with the resulting improvements.

    The only thing I've done to mine so far is to quasi-dry-fire (I say quasi because I catch the hammer with my weak hand finger to avoid having it actually hit the firing pin) about 500 times. That has very noticeably improved the trigger feel already.

    If you try that kit please report back your impressions!

    Will do. Probably doesn't help that the only two times I've shot it, I also had my Kimber 1911 out.

    What a coincidence. My other 45 is also a Kimber (with a very good trigger).

    You can use an O ring instead if your finger to prevent the hammer from striking the firing pin.

    CZ 97Bs always need to be well-throated to prevent jamming.

    I've done that too, but I also recock it with the finger and you can run a couple of cycles per second and get the count up pretty fast. A glove or band-aid on the finger helps if doing a lot of cycles.

    That was often reported to be the case on some of the pre-2013 models when shooting certain hollowpoints, but not the case on the new 2013+ version.

    I would be interested in learning more about this . . . . .

    As ITurbo mentioned, early 97B models needed throating (mainly, properly polished feed ramps) to overcome being jammatics with anything other than FMJ/ball ammo. Reports were fairly numerous, here and elsewhere, of 97Bs choking-out on JHPs of various makes.

    Not saying current 97 models aren't righteous .45s on the CZ-pattern; just reporting a historical fact. :scrutiny:

    Funny, though, my ancient Colt .45 has swallowed everything I've ever fed it, all day every day. :neener:

    I believe he meant reaming the chamber rather than throating. Have you not reamed undersized chambers in the 97b to get them to feed reliably?

    CZ made a few changes to the barrel over the years. They started with a short feed ramp and no barrel throating, then gradually lengthened the ramp twice. The locking lug on my 2010 sheared off and the new barrel has a longer ramp along with decent throating. I'd still like to get it reamed a bit as the leade is practically nonexistent.

    David at CGW has been very helpful with my conversion to SAO along with the cool 1911 bushing conversion.

    agtman,

    Schmeky is David who owns Cajun Gun Works. He is one of the resident CZ experts. I may send him my new 97B to tune although it really doesn't need anything. His work is top notch.

    A little taste of his work.

    In ramped barrel semi-autos, throating means increasing the freebore, or lead to accept bullets with a longer OAL.

    In the 1911 design, which has no ramp, per se, throating implies a wide radius on the barrels lower edge to allow it to feed semi-wadcutters.

    Obviously these are not the same.
