the .45 auto is a nice shooting gun. you can shoot it with one hand and be very accurate it needed.a full size frame has very little kick to. most shots for defence are 3 to 4 yards. i think the average shot is 7 yards. we practiceat 20 to 25 yards and play around alot at 50 yards with the .45's. doing this just seems to make the closer shots come easy.the thing for defenceis to practice and practice so that you never have to think about the gun if it is called apond.the biggest decisionshould beto use the gun, not how to use the gun. go for the .45 you'll will be very happy with it. those 1911 models are a ton of fun to shoot.
