Patton thanks for sharing. There definitely seems to be some sort of issue as we should not have to be tapping the slide or muzzle for it to operate properly. I sent my gun in last week and just received my RMA number today. I say don't take any chances and send it back to S&W to get looked at and/or repaired. Hopefully S&W sees there is an issue if quite a few people are having the same problem. Just my 2 cents.
