.....
To be more specific: I paid $320 cash for a lightly used PT92C after talking the pawnshop dealer down from $350. It is a blued model, not SS. Wood grips, one 13-round clip. Then found extra 13-round clips (one at a time) on eBay for 10-20 bucks each. Ebay recently banned clips for sale, but occasionally some still slip past the listing "police".
Recently bought a 20-round (extended) clip for the 92C from MidwayUSA. Last time I checked, they were out of stock- but could still special order them.
New clips are available, but ya have to do some digging.
I really wish I could find some extra GRIPS for mine. GRIPS for the 92C are impossible to find anywhere. I have tried for months to find a set. Mine are in fine shape, but I prefer rubber over wood- darker, harder to see, and easier to hold (in my opinion).
Your price of $360 sounds reasonable for a good condition SS model, but I'm not an expert. Sure don't see many of these around in SS nor blued.
Glad if this helps.
