So I brought a tm p226r last weekend and used it yesterday fresh out the box. I was having issues with the slide sticking, I’d forgot my silicon oil so couldn’t sort it yesterday. I’ve got it out today and took the slide off. It was all pretty dry so I’ve lubed it up, but noticed there was some really rough areas on the metal above the trigger (see pictures) and wondered if it was normal or if should I file them down.
