I'd get one of the Yugo M-57 Toks from SOG. They cost $229.95, with shipping and transfer you'd be at $275 or so. Then go to AIM and buy a 1224 round tin of Romanian 7.62x25 ammo for $120.
It is not a cheap gun by any means. It is a very strong durable pistol. The 7.62x25 round is a screamer, it will penetrate Kevlar helmets and Level 2a vests.
