Hello. The price sounds good as most go for around $320. I'm not aware that CZ's making these in stainless; could it be e-nickled or hard chromed?
As to accuracy: Expect 100% reliability and very fine accuracy. I've only shot a couple of these besides mine and all had their sights well regulated from the factory. Groups were very good as if often the case in .380 pistols as many have fixed bbls and slides that fit the frames well.
CZ83, while not the smallest in its caliber, is one of the best shooters I've found. It is my favorite .380 ACP.
Best.
