The informal competitions could have plenty of CZs. But most formal competitions (ISSF approved) are either in .22LR caliber, or big bore (.32S&W preferred). The professional weapons are also the ones that you see in Olympics mostly, dominated by Walther GSP Expert/SSP, models from Hamerli, Pardini, Benelli, and even Baikal etc. CZ does not have a product line for those competitions. However, in informal big bore (.32 or above) competitions, a good CZ75 variant (75 SA, Shadow Target, TS with adjustable sights etc) would be hard to beat, unless one is using
-.32S&W Long revolver, or any other revolver
-SIG P210
-Tuned/Custom/Match 1911s
-SIG P226 x6
-HK mk23
-HK USP variants (elite, match etc)
-CZ Clones, the better ones
Then, it depends alot on the shooter. I primarily shoot bulls eye, and while not very good, below are some of my best with CZ variants (I keep posting them all over this forum, you see, I am very excited of what I ended up with on these better days of shooting!)
Distance: 25mtrs (27.5yds)
Grip/stance: Double hand grip, unsupported, standing.
Shooting Hand: Right

The SP01 was shooting an inch to the right, even in the test target. Infact, I managed to better the test target in group size by 10mm! The above group is just around 2".
Distance: 25mtrs (27.5yds)
Grip/stance: One hand grip, unsupported, standing. (Olympic style!)
Shooting Hand: Right


The above 181, with a some more practice and hard work (or by a top level shooter), could be stretched to close to 187-188, specially if were to use hand loads. I have used Chinese Norinco +p 115gr 9mm for both above. The same, with a revolver, or a .22LR/.32S&W match pistol and match ammo could cross 190 easily, with recoil (or lack of it) being one of the major factors. These are fixed barrel, and definitely more accurate than any other type of auto out there.
