I've heard this claim before, but not the reasons for it. Are you saying that the fact that the CZ barrel doesn't tilt improves accuracy?
I'm saying by mechanical design, in my opinion, the CZ has the potential to be a more accurate design all things being equal.
With in spec rollers and fresh recoil spring (no loose breech) I believe the CZ with less barrel to slide action, should by consequence of that, lockup more consistently so by rights (with a slightly longer barrel also) be the more accurate design.
I'm not saying the CZ is the more robust or reliable design, simply the potential to be more accurate. Apparently the Czechs didn't help matters with their QC issues of heat treating and what not but I believe some of these so called refurbished 52's (black ones) are nothing more than refinished.
Some of the 52's out there people claim are so inaccurate most likely have loose breech with trashed rollers and worn recoil springs slamming the hell out of everything which not only ruins the barrels but makes the pistol flat out dangerous. If your brass is being thrown into the next county, and you can't hit what you're aiming at, here's your sign. :banghead:
The rollers and recoil spring were intended to be replaced as common maintenance yet how many are out there completely worn?....My 52 looked practically unissued when I purchased it and I still went ahead and replaced the firing pin with a machined one, an extra power Wolff recoil spring and hardened rollers and would highly suggest this to anyone who owns a 52.
The CZ is definitely a tinkers pistol so if you're not into that, than get the TOk.
With quality commercial ammo (S&B & PrVi) and in spec action and trigger job, my 52 is dead eye accurate....YMMV
