Yep. Ask for that at a big box store and they'll look at you funny. Probably something to do with liability issues.Yep, that was one of the reasons I would go to Bradis. Mark would install my Glock sights (when he was still there) and Kenny would do the M&P stuff. Kenny actually installed a few things for me.
Hell, back when Gander was in business (and before I knew of folks like @Squirt239 ) I took dad's TOTALLY disassembled 36-1 to them to reassemble. It was in rough shape with surface rust and some pitting. They reassembled it, and then warned me it was not safe to shoot on the paperwork when I picked it up.
It was just minor pitting. structurally it was still sound. Even I knew that. "Sorry, its our policy to state that anytime we service a pistol that is rusted." I politely suggested that in the future they might want to warn a customer of that during drop off. Maybe I didn't want to pay to have it reassembled if I couldn't shoot it? After all, that is the whole point of getting it reassembled properly. If I wanted a display piece, I would have just taken 60 seconds to put the grips back and put the cylinder back on it.
EDIT then I did find out about Squirt and he did an AWESOME Cerakote job on it. No more rust issues.
