Hi all, I've got a brand new G17 that I've put 200 rounds through. As can be seen in the pic, there seems to be some excessive wear to the front rails. It looks like a thin layer of silver colored metal has been scraped off of each rail, and a copper colored metal underneath is visible. I dry fire it a lot, more than actual firing at this point, and I live in an apartment so I need to control the racket that frequent racking of the slide makes. In so doing I pull the slide back only just enough to reset the trigger, which often does not provide enough spring tension in the guide rod spring to push the slide back fully into battery. I often need to give the slide a slight tap to get it to fully seat. When this happens there's an audible ping sound that comes from under the slide near the front rail area which leads me to believe this is the source of the contact between the rail and slide that's causing the problem, but I can't tell whether it also happens during regular firing. I have replaced the stock guide rod/spring assembly with a SS rod with a factory weight spring. Has anyone seen or experienced this problem? Should I be concerned about the damage, or is it normal wear? Any solutions? Thanks, Chris Wanna kill these ads? We can help!
