I had a new STI a few years ago, that I purchased from a dealer out of state, and the slide release was scratching the slide. I called there customer service and asked what they could do, and they said they could refinish the slide, if I paid for the work and shipping both ways. I asked to speak with a supervisor and he told me the same thing. I sold it to a local shop the next day, and will never own another STI.
