My primary carry is a varient of the 3913. My primary right now is a 3953 with a M37 w/bobbed hammer BUG stuck in the front pocket and a 4053 (Single Stack, No Rail) as a truck gun. I rotate between the 3953 and the 4053 as primary carry on about a monthly basis but always have the M37 in the front pocket. LUVS ME SOME DAO!!!
