I had a S&W 9mm done in 1999. NP3 frame and internals, Rogard slide. It took longer than they said it would. The Rogard started chipping off of the breechface area inside of 50 rounds. Sent photos off to Rogard, they said it was "their bad," fixed it pretty quickly. No more problems after that, and I put quite a few rounds through it with NO chipping in the area. Looks good. The NP3 was wearing, I thought, and I saw a Rogard guy at a seminar and showed it to him. He said it was just polishing it, not wearing off, but offered to fix it to MY satisfaction free of charge. It wasn't worth messing with, but how can you beat customer service like that? If I had it to do over again, I would Rogard the entire outside and NP3 the internals only, that stuff is like a trigger job and, as mentioned above, speeds clean up.
