I had one of those in the early 90s. It was beautiful and shot great. In fact, it was one of the best shooting pistols I've ever owned. I had to sell it though; times were lean back then. I think about it every once and awhile. :'(
Wow! $500. I didn't pay that for my PT 92 with a third magazine, and sales tax. (7%) And mine has the newer de-cocker/ safety. This was just prior to the list price going down $98.
So, I guess he's $100 over priced.
should be able to use a standard 24/7 C 9mm magazine in the PT92 C. Although you will need to make a notch with a dremel tool for the PT92 Mag release, but thats a simple thing todo. And that works both ways of course...
