    CZ TS 2

    Just look at all limited guns. Do you see any that are made with heavier slides? No, the race guns have slide cuts and even slides that are shortened, to make the moving mass less. 


    You seem determined to confuse what works for muzzle dip (light slides, reduced weight recoil springs) with a somewhat magical reduction in recoil. There is no free lunch, forces must balance. 


    It is interesting to consider barrel weight's effect on felt recoil. While slide to barrel is initially locked the barrel should effectively act as a slide weight and then the barrel momentum should transfer to the frame through the barrel link & etc.

    In your formula you did not take into account the losses due to friction, heat differences and a million other small factors.😀😉


    That comes from engineering & physics classes. There are always a long string of minute influences that tend to zero for all practical purposes.


    When you weigh yourself on a scale you likely do not factor in the variance of weight do to the relative position of the moon, for example.

    Exactly, this is also a valid point - to the advantage of the bull barrel. You want the weight to be stationary like in the barrel, the moving weight in the slide actually adds to recoil. So less weight in the slide and more weight in the front of the barrel means win-win for softer recoil and less muzzle flip. 


    Less slide mass IS better for recoil. A heavy slide feeds better though and is less sensitive for dirt etc. 


    Not sure about that.

    On the way back, F=M*A, so you can have less mass and more speed or more mass and less speed but you have to counteract the same force either way. 


    For dip on slide closure I think the you are right.

    Production is interesting to me because the 10 round limit changes the sport so much. 


    Yep. When I switched back to limited for a time it felt like I was missing out on a lot of what I enjoyed, when you hit your reloads slick and feel pressure not to miss that steel and force a reload that is the good stuff. 


    I would like to see the limited division rules tweaked to allow big stick mags in limited minor for those that do not enjoy the planning/reloading/accuracy challenge of low capacity shooting. Limited major would need to retain some advantage to prevent devaluation of existing guns but I can't see a 9mm big stick changing much besides making room for those folks who hate reloads.

    I guess CZ isnt sold on the bull barrels. 

    Not sure why everybody else is. 




    Me either.

    Les Baer guarantees everything to do a 3" group at 50 yards and for an adder 1.5" at 50 , so the bull is not about practical accuracy in a pistol.

    Maybe longevity?

    I agree. Just don't drop your mother f***-ing gun, ok? 


    Rob Leatham rather famously dropped his gun for a dq at the single stack nationals, and I have seen a local gm with long experience drop a gun as well.


    s#!t happens.

    I just fiddled around with a couple S2s and it seems if you are super concerned about this particular failure mode (I am not), then the answer might be a light firing pin return spring. 


    If the return spring is light enough, the hammer pushes the pin in and rests on the firing pin stop when its down.  Yeah, it can transfer force if whacked hard enough, but if the spring is factory-strong, it pushes the hammer back a tiny bit so the hammer can get a miniscule 'running start'.  The physics gurus can sort out which is more effective an energy transfer.




    When I dropped my CZ and it fired the bullet hit the concrete. I don't think that is possible if the gun lands on the hammer.

    Agreed...the lower-powered firing pin spring in particular.


    Maybe. Length and weight of aftermarket pins also seems like a thing, and perhaps neither would be an issue with other than federal primers.

    If there is any truth to the story it was a cz without a firing pin block


    I'm coming into this thread late and haven't read all 7 pages, but anyway for what it is worth:

    I came forward on the draw with a CZ 75 CTS-LS (no firing pin block) before the barrel cleared the holster during practice.

    Dropped gun landed on concrete and fired.

    After cleaning my shorts I found that the bullet marked the concrete as if it landed muzzle first between my feet.


    The gun in question had an extended firing pin and a reduced weight firing pin spring - the ammo had deep seated soft federal primers. 


    I sent a notification to CZ Custom when it happened and have made a comment or two about it on this site previously. I just noticed that that particular gun has been discontinued.

    Direct from tanfoglio or Eric Grauffel. I have both 1.5 and a 1 (Xtreme) It’s a factory tanfoglio FO front sight usually found on the limited custom.



    Just sent a couple emails asking for part numbers to get the 1.5, from either website I can't see where they clarify diameter although there is one part called out as a 1.0. The kind boss lady at Patriot Defense is checking around for me as well. 



  7. My old eyes really love the fatter 1.5 mm fiber shown on the left and the 3.0 mm width of both the sights shown.


    Anybody know where to find one?


    Thought about just drilling out a 1.0 mm fiber sight but I think that would be tough (base below fiber would somehow need lowered or channeled, can't just open the holes). 


    I think  I got the fat one from EAA a few years ago but am not certain and have not had any luck contacting EAA to verify and ask if they will ever get one in stock.

    At a local match. There was a V shaped stage. I wasn’t on the stage when this happened, but the shooter was towards to the point of the V on the left side and the RO was at the point of the inner V and when the shooter crossed over to the other side of the V. The RO was now in front of the shooter. Lucky no one was hurt.


    Have seen the exact same thing at an IDPA match. 

  9. FWIW.


    So far the best load I've found is 180 Bayou 3.9 Clay Dot (pretty similar to what my 625 liked).


    Still looking. 


    With mixed head stamp range brass and Federal primers the gun has been 100%. No tweaking yet beyond the McCarbo kit (shims - reduced hammer spring - reduced trigger return spring) and some polishing. No indication of any brand of spent brass wanting to stick, which may be due to shooting just a smidge above IDPA minimum power factor (155) rather than a hotter load.

    8.3.1 could not be any more clear


    Have you read it?


    Thank you for that very constructive suggestion.

    It is people like you who read a thread before responding, and help others in a good natured and friendly fashion, that make the shooting sports great fun.

    Sooo how often does a competitor load his gun before LAMR?


    And also, if you jump up and down naked during a course of fire while screaming "Krishna Krishna Hari Krishna" and flapping your arms like chicken wings, that is a dq under 10.6.1 .

  12. Is there

    Dude ...


    If you drop a gun DURING the CoF (as described in the OP) it is a DQ, loaded or not.  The gun WAS loaded and he dropped it.  It was loaded because he loaded it during the CoF ... He's DQ'd because he dropped it.  The fact it was loaded is what we call in the trade, a clue that it was likely DURING the CoF.


    Were it NOT during a CoF and it was loaded he's DQ'd because it should not have been loaded.


    In short, it's IMPOSSIBLE to drop a loaded gun and not earn a DQ for it!




    The question that inspired this thread (confirming definition for the start of the course of fire) was answered in the first response and apparently there is nothing in the rules mentioning whether or not a dropped gun is loaded. 


    I got it, not sure why there are multiple posts explaining the immediately obvious.

    he either dropped a loaded gun and was thus in the CoF so he's DQ'd, or he dropped a loaded gun that was not supposed to be loaded and he is DQ'd for that.



    After there is a correct understanding of how the start of a COF is defined, sure.


    Else, if any rules related to a dropped gun mention whether or not the gun is loaded I have not found them or seen them referenced here.

    2 - I the gun was loaded then it SHOULD have been during a CoF ...


    Confirming how the rules describe the start of a COF is sort of the whole gist of this thread.
