According to my testing:
Dominion Arms P762 –
Chinese pistol derived from the excellent Sig P226 but stretched to handle the more powerful, flatter shooting, historic 7.62X25 round. Chrome-lined bore! A blast to shoot and stupidly accurate. Accuracy comes, in part, from a seemingly tight chamber in the neck area. This creates reloading challenges. Forget about reloading easier to find 71-95 grain .309-.312 bullets – including lead cast sized bigger than .309. Tight neck means that some hot surplus 7.62x25 steel case ammo will stick in the chamber – which doesn’t in the other two. Case head and feed ramp area not well supported. Double Action trigger is too heavy to be useable. Doesn’t throw its brass as far as the M57 or the TT. Supplier has seriously reneged on promises to bring in extra mags – by at least 2 years! Some Americanskis would pee their pants if they could buy this gun. They can’t.
Tokarev TT33 –
Totally underrated design! Beats anything else from the era for long range performance (look on youtube for the guy hitting an 80-yard plate over and over again - off hand - with a WWII era T-33)! Removable trigger sub assembly is cool and practical. WW2 Nazis hated these things. Cheap with affordable mags available everywhere. Surplus ammo available starting at $5 a box. Better gun than what the Ruskies adopted afterward.
Zastava M57 –
Great quality – especially for the crazy low price of these BRAND NEW pistols. “Ups the game” of the Tokarev TT33, especially with the slightly longer grip that holds a 9th round. The magazine safety - found on newer production guns - is worse than useless – but easily snapped off – allowing for a clean mag drop. Accurate gun but most units shoot very low with fixed sights. Front sight already too short to file down and taller rear blades are not available - so I hope you know a good gunsmith. Captive recoil spring is a great improvement over the TT33 design.
We Canadian should have the choice of buying the M57A which has a nice FACTORY slide mounted safety (and no I'm not talking about the goofy US import guns with retrofitted safties). Also let’s all get after the importer to bring in the excellent Zastava factory optional one-piece rubber grips – shown in the photo. It would save the rest of you a trip to Serbia (although it is nice there at this time of year).
To you CZ52 guys – sorry I never had my hands on one.
