I found a listing for the late, lamented .32NAA in a pawn shop. Way too far away to inspect the gun myself. Picture of the left side looks a bit scuffed but no obvious problem. What are my risks here? Is the barrel likely to be worn out? Is it a separate piece like in a 1911, that might conceivably be replaced without too much trouble? I know ammo is a problem. I can deal with that. How likely am I to be able to find one of these in good shape? I'm a little skeptical about a pig in a poke, but I'd really like to have one of these. Guns.com frequently has used guns that are "certified" and they offer some kind of warranty. For all I know the people selling this may not even know how to load it. Advice?

Man, these robots that insist on ever more difficult tests to prove I'm human are gonna get sued for discrimination like that police department that tested candidates for arithmetic skills.
