Very fun round. Zips by at 1600fps at the muzzle out of a 4.5" bbl. Ammo is the cheapest center-fire round out there. $130 for 1224 rounds by my last count. I find the recoil to be about 2/3rds that of a 9mm. Very easy to control.
It is corrosive, but it is also Mil-Surp, so it comes with all the pluses and minuses of Mil-Surp. Round also exhibits destabilization in a fluid medium leading the FMJ bullet to yaw. JHP Is scary.
The TT33 is almost like a revolver in feeding. Each round is fed almost directly INTO the chamber. The feed ramp is almost completely unnecessary. It shares this feature with a S&W 1006.
As for some mythis I saw crop up: A TT33 is much stronger than the CZ52. This is not true by simple virtue of the TT33 having a significantly thicker chamber wall then the CZ. The CZ52 has a milled cutout on the bottom to make room for its roller-locking mechanism, that leads to the bottom chamber wall being quite thin. For more info, search the member "clark" or just read this thread:
The definitive TT33 thread.
Basically, the TT33 will shoot itself loose into a rattle trap, but will never bust. A CZ52 will lock up rock-solid each and every time, right up until it hand-grenades.
Ergonomics: The TT33 is meant to be held with one hand. This is because the gun was designed A) At a time when sidearms were seen to be in the same category as officer's swords, and B) The style was one-handed shooting for pistols.
With that lineage, the TT33 grip angle is surprisingly ergonomic. It is a little more vertical than a 1911, but once you pick it up, the gun seems to want to snap onto target. It is very easy to aim and shoot, and it easily snaps back on target after each shot. Also the front strap angle is the same as a 1911, which seems to be more vital than the rear-strap angle as far as ergonomics goes.
Some shooters will not like the short grip on the TT33. It is just barely big enough to grip with an average sized palm. Basically its a sub-compact length grip.
Trigger is a very good military SA trigger. Depending on wear it may have some grit or be very smooth, short and crisp, like a revolver or a 1911. Polishing of the trigger reset leaf spring will improve the smoothness.
Gun breaks down exactly like a 1911, only different detail is a retaining plate holding down the slide-stop.
Trigger pack is made up of 3 parts and is a self-contained module that is easily removed (see: falls out) from the gun for cleaning or maintenance. If you ever wanted to try DIY trigger jobs, its is a good gun to learn on.
Safety: One of the bigest myths about the TT33 is it has no safety. This is utterly false. It has a safety integrated into the hammer. The half-cock notch is the safety of the TT33. At this position, the hammer-pack
locks both the trigger and the slide. The gun is now "half-cocked and locked." The only way to return it to function is to pull the hammer all the way back. There is no firing pin safety, so if the gun is dropped from a tall enough height it will go off. But, short of a 30 yard fall or hitting the back of the gun with a sledge, it will not go off "half-cocked".
Oh, and since the 7.62x25 round was adopted from the .30 Mauser, it is one of the few (only?) Russian 7.62 weapons that uses a true .308 bullet instead of a .311
