That Chiappa M1-9 looks interesting. I'll have to keep my eyes open for that one.
Everyone has memories of guns they should have bought when they had the chance, but didn't. One of mine is a Marlin Camp Carbine in 9x19. It was one of the early ones in 9mm, handled nicely, I don't recall what magazine it took except it was not a Glock as they are made now (I want to say it was for the Walther P-38 but I am probably wrong). But I checked it out and found the buffer, which looked like a thick white plastic washer, was partly melted, and that replacements for that part were difficult to impossible to find. So I passed on it. A couple of months later, I found a source for the buffer and trotted back to the gun shop, but someone more knowledgeable than I had glommed onto it and it was gone.
Next time I will trust my instincts and buy it first, and worry about replacing the worn part later.
