Rifle: The Barret M-82/M-107 .50 cal rifle. The recoil isn't bad due to an efficient muzzle brake, but that brake requires double ear protection and is probably part of the reason I have tinnitus. I wouldn't shoot one recreationally, but on the job, well ya got 'a do what ya got 'a do.
Pistol: 1911 (original GI), not the 1911A1. The short grip safety allows the hammer spur to cut the heck out of the web of my hand unless I wear a glove.
Shotgun: 870 Supermag with 3 1/2" shells. Sometimes when shooting geese I don't notice the recoil, but mostly I do. Of course the geese don't think much of it either!
