I'm shooting the S&W IDPA Winter Championship this week. They had a product demo last night at the Shooting Center and had all the M&P's available to shot. Shot both versions of the 45. Fantastic guns. Low recoil, great fit, accurate. Spoke to Joe Burgeron product manager. The saftey as I understand from him doesn't lock up the slide like a 1911. You can rack the slide and clear the gun with it in safe mode. I think he said April for shipping.
