I'm a Glock guy and I also like my Kahr. I shot with a friend yesterday and wanted to ask those in the know about S&W autos this question. My aquaintence, because a friend would have listened to me better, bought a Sigma in 40. After about 60 rounds I notice that one of the dissassembly pins is almost all of the way out of the gun. This is a new gun, never fired before that day. Should he send it back if the pin continues to walk out? I just took a screwdriver handle and tapped it back in and we shot some more. If the pins came out of my Glock ever 60 rounds I would go nuts. Live with it or send it back? Or sell it and buy a better gun. I like the M&P even though I am a Glock guy, but the Sigma isn't for me.
