I bought one of the new M57A's in 7.62x25, and I have to say, I love it.
Mine is not "gritty"...after clean and lube and 100rds at the range, it is very smooth. I shot 70rds of Romanian surplus, and 30rds of S&B commercial FMJ...not a single failure.
I find the slide mounted safety to be easy to use...it is long enough to flip off with a firing grip. I would have no problem carrying this pistol cocked and locked, though I wish Zastava had kept the half cock of the original design.
Dans Ammo has Yugo mags, and I ordered up two for spares.
The finish is very nice and well polished. After having owned several surplus Toks, I have to say that the new Zastava is certainly the best. Mine has a three digit serial...000070X
I agree with jhb...a 9mm Tok dosn't hold much interest for for me. Part of the joy of shooting the Tok is the hot, flat shooting Tokarev round.
I have shot Toks out to 100yds...basically, if I can see it, I can hit it.
I have a sealed can of Romanian...I sure hope some ammo comes in, I don't want to open that can.
