I just bought a brand new M&P 22 Compact first trip to the range after 30 rounds. The rear site fell apart, and I lost the rear site when did adjustment screw and spring. Smith & Wesson‘s response was terrible stating that rare sites for that gun are out of stock and they have no idea when they will be able to send me a new one.. by then asked if I could just order the parts and they gave me the same answer. I’ve been on all the aftermarket sight sites and every aftermarket one is coming up as out of stock. Also, can anyone help me find an aftermarket sight or parts for the original sight or does anyone have one to sell thank you for any help with this matter? I believe the gun will be a good gun, but however, I can’t determine that without a rear sight.
