Went to a local gun shop in my area and they have a few law enforcement trade in USP .45 full-size models with the stainless slides. The gun shop has them priced at around $580, which I think is a good price for a USP .45, however, they have considerable wear and blemishes on the slide/frame, mostly on the slide. I can only guess how many rounds have gone through these. The gunshop employee mentioned that they used to belong to the Broward county SWAT team and they traded them in for newer models. I'm thinking SWAT members probably practice with their guns more often then other police officers, just a guess. Anyways I have 3 questions: 1. Do you think $580 is a good price? Might be able to negotiate a couple bucks off. 2. I love the stainless finish, but it looks like it has to be redone and H&K doesn't do that at their factories. Where can I have the done and how much? Can I polish the slide myself by sanding, polishing with Mothers/Flitz etc? 3. This would be my primary defense gun, so I need it to be 100% reliable. What parts can I purchase and swap out to make the gun good as new?
