I had picked up a M&P Compact, went to Bowers bought an Ameriglo front night sight and the Apex duty/carry kit, MIke gave me great prices on them-Rob installed them on the spot. Later on I knew I wanted a full size, Rob removed those parts, I sold off the Compact, found a great deal on a full size, went in and Rob installed those parts on the full size while I waited. I've done other small purchases over the years (6 postion tube on my 6920 was my latest, again installed on the spot). One of the few places I don't feel bad leaving with less money than I walk in with lol.
