I have one of the older German made ones and have used it for a winter ccw for over 12 years.
The original night sights still work but not like they once did, you can pick up one of these used for about $450+ .
They will eat anything including lead swc's. and even though you can get cheaper magazines to function well in them for trips to the range theres just no beating the factory ones with the dovetails on the back.
I've never had any problems with mine but have ran across guys who have and you can just about bet they've stripped the frame down for what ever reason and not reassembled it correctly. Stripping the slide, pin punching out the trigger block to clean is no biggie but why practice gunsmithing on your carry piece? Good design, great caliber, last thing I'll ever sell off.
