After years of carrying a 9 mm I now carry a Rock Island 45 acp. It is single stack but still a hefty piece of iron. What sold me is the bull barrel.
Up to a couple years ago I used the normal stance (shooting arm out straight.) I have changed to a Weaver stance, modified somewhat. I found myself “pushing” when in the normal stance and this modified Weaver stops that. It also makes grapping an extra mag easier.
Using an inside the waistband holster or other type of holster made huge bulges in my shirts. So I now carry without a holster. I always wear a undershirt of some kind to keep the metal off the skin.
Having said all this I have found that this weapon does require a tad more TLC than I am used to supplying. No problem doing this as long as the gun runs correctly when needed.
