Probably just not feasible, but I have many pistols and the 1911 is what I’m best at. I carry an LCP MAX and some other .380s, but I’m not so hot with those. Also have a slightly larger Ruger 9MM that works great. Just about can’t miss with the Colt Government Model.
I suppose the answer is to practice, practice, practice with the smaller guns?
Though also if you plan to appendix carry, it would be good to look into how safe the 1911 is for that. Since it’s an older design, there may be additional concerns about having it pointed at your femoral artery.
