Well, I just bought a brand new Zastava M57. This is the new clone of the TT-33. It shoots 7.62x25 and has a few structural differences from the original. It has a magazine safety, so you can't shoot without a magazine in place in addition to a regular safety. It came feeling pretty rough and I had a hard time working the slide. But this improved with the initial cleaning. The trigger is a bit heavier than i like. When i got to shoot it, i was disappointed to find that it shot left and very low. It was only after 30 or 40 rounds did i discover that i was really rusty and need to get out and shoot more. After a while my shooting skills came back. But it was still shooting a bit left and low. I noticed that the sights were dovetailed and though it is sold as having fixed sights, i took a punch and hammer and made a slight adjustment. When i felt that my shooting was at its best, i put 9 rounds of my Romanian surplus at about 25 feet and you can see the results. Thats about the best i can shoot, so im very happy with the gun. Once it breaks in i think it will only improve.
