Customer service, reliability, quality....... If you are looking for a gun that size chances are you are planning on carrying it at some point. I know a couple people that owned the mil. pro in the past in the .40 and the .45, both of them no longer own those weapons due to reliability and customer service issues they had. That being said I know alot of people on the internet in various forums that really enjoy the gun, I just don't think I could trust it enough to be my carry weapon.
