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?
Isn’t it the opposite? Heavy slow round like a .45, less penetration behind the intended target? Of course JHP vs. round ball makes a hella difference, so there’s that.
You may be right actually… this is what I was going by and I had thought I remembered the .45 going further but it actually just clears it just like the 9s
Now that you got me curious, I did some more reading and you are right: 9mm and .45 acp have the same wound tracks but 9mm has more penetration
