My CZ 75b and IDPA

    I have yet to make it to a IDPA match but before I get around to it I was wondering what in my gun will keep it from being in stock service pistol division maybe it's fine?

    Upgrades on the pistol now
    Polish trigger job
    CGW trigger Pin
    Comp hammer
    13lb hammer spring
    recoil spring buffer
    extended firing pin
    reduced firing pin spring
    reduced firing pin block spring
    wood grips
    grip tape

    and I think that's it right now I would like to put a 85b combat trigger on there if there doesn't change the division as it's a part from the factory, a CGW firing pin retaining pin, and some better sights. I read the IDPA rules but they seem pretty vague so I was hoping someone could clear this up for me.

    I thought they were pretty clear, perhaps you can point out the vague portions that are causing your confusion.

    The CZ75 can be shot in SSP or ESP, depending on you choice of stating condition of the action. If you compare the allowed alterations for each class, you shold be able to determine if you will qualify to shoot in SSP

    The CZ85 combat trigger has a trigger stop that would throw you into ESP.

    The other stuff you list is apparently ok for SSP being either specifically authorized (grips and sights) or internal.

    I wondered about the hammer.
    If you had the distinctive Cajun hammer, it might indeed get you moved to ESP.
    If it were a CZ item or an aftermarket very similar to stock, probably not.

    Actually I think you will be better off practicing things like use of cover and the concealment draw (which can be done dryfire), learning the rules, and getting the new shooter orientation at www.gadpa.com than tinkering with the pistol (more.)

    The hammer might also get you bumped into ESP, but I'm not sure

    If the hammer is a non-factory externally visible part, welcome to ESP.

    "Looks like" a factory part is not the standard; it must be a factory available part.

    If the trigger you are contemplating actually replaces the trigger/shoe itself (externally visible) with an aftermarket part, it too would by itself be a ticket to ESP.

    Nothing wrong with ESP. Don't worry about the gun; go shoot, if you decide you like it, worry about getting 100% in compliance after a couple local matches. No one is likely to stress over minor details on the gun at your first match unless they are way more wound up than any club I've ever been to. That said, if you keep at it and/or enter any major "sanctioned" matches you will want to make sure you are 100% in compliance.

    here is the hammer

    It's a part made from the factory but wasn't an option on my 75 I don't think.
    If the hammer works than why wouldn't the trigger? It's also a part from the factory made for the CZ 85b which would be a 75 variant wouldn't it?

    Both the hammer and the trigger would be factory parts now the CGW trigger pin is not and is externally visible as you can see both ends of it.

    Hammer is probably ok.
    The 85 trigger has an overtravel stop, which is specifially allowed in ESP but not mentioned in SSP. IDPA specs are "inclusive" meaning that just because it isn't disallowed does not mean it is allowed when it is not specifically listed as allowed.

    Frankly, I doubt if anybody would notice one way or the other, but that's the rule.

    Thanks Ya I was wondering what the rules were they seem to be worded harder than they should be.

    I've never used a trigger with a overtravel screw anyways so if I'm missing anything I wouldn't know it.

    Basically if something isn't offered from the factory on your model gun, and you can see it, it's an illegal external modification for SSP.

    It's good-to-go in USPSA production class as it is now. With the 85 trigger with O.T. adjust, I'm not sure.
    It wouldn't be OK in IPSC.
    I also shoot the 75B with similar improvements.

    Since I'm in Iowa there isn't a whole lot to choose from and IDPA is my only option I could find that's within 50 miles. Thanks for the help I fell that I have a little better under standing of the rules, I also plan to go up and just watch and match and meet some of the people if I ever get some free time.

    If you don't have all the necessary gear, they'll either help out or make adjustments to let you shoot. You will love it.

    Weigh it. My Witness 9mm makes SSP for function, but not for weight. Its 42 ozs. SSP is limited to 39 oz pistols, ESP allows up to 43 oz pistols.

    But for most club level matches it wont matter, so if this is your first time, go out, shoot, have fun, worry about the details later.

    I think it's 34ish stock. Is that loaded or unloaded? I'm gonna order me some CGW sights and the firing pin retaining pin. Still haven't decided on the combat trigger as I'm not sure it's something I even need I was hoping I could use it with CZC SRTS but that's for none firing pin block guns. Just would be a nice combo I think if you could remove both the pre/post travel on a DA/SA gun but I may be dreaming.

    Alright just had a another quick question to add to this, The CZ 75 shadow with the over travel screw is legal according to CZ custom.


    So now I'm confused a little again, why is this ok?

    Also what about stock mags, if you cut the follower on a 16rd mag and use two small screws to tie the spring to it you can get it to hold 17rd's tho I haven't done enough testing to see it there as reliable.

    Why would it NOT be?

    And regarding the mags, what's the point of modding a magazine to hold 17 rounds for a sport that allows no gun to be loaded beyond 10+1?

    The mags is something I didn't know I'm still reading up on all the rules and haven't got out and shot at a match yet.

    Well if it's allowed on the CZ 75 shadow why won't it be allowed on the CZ 75b as there are both 75 models?

    Without looking at everything on the market, I would guess that an aftermarket trigger stop on a CZ75B might be an external modification and the factory stop on the Shadow is internal.
