I just received my M&P pro 9 back from S&W customer service. One week turn around, not bad.
I had sent it in as it would randomly not reset the trigger when fired.
What was bad is that they did not reinstall the take down lever. It was missing. I could not disassemble the gun and had to send it back again. Bummer.
Yes I know what you mean. A few years ago I tried to order a different front sight for my 625. Because they could not install it (for a fee) the guy I was dealing with refused to sell me the sight.When I asked why they could not just sell me the front sight the response I got was the click of being hung up on. pretty sorry service even if it was only a 10 or 12 dollar part.
