Shoulder bag? I think you mean a murse.
Man-Bag, **g-Bag, call it what ya will. I'm 6'1" @ 300lbs and I have yet to have my manliness questioned. Fact is, I ride a wheel chair any time I am out an would have to walk very far or stand very long and getting to pockets or yer belt is... obstructed. I started using a fanny pack but wanted something more functional and made to carry a gun in and bought the "Unisex" bag from E. S. Ramey.
Back to the topic: While the biggest I carry is my 1911, my go-to daily carry is my KT P11 as the 1911 is HEAVY! I am heavy enough without adding any extra weight to my failing chassis!
