.45 ACP is clearly superior to 9mm. But there are a lot of comparable personal-defense items that the jury is still out on. Whether you want to share your opinion or gain some insight before your next purchase, this is the place for you!
I have carried a .45 ACP for 20+ years in law enforcement as well as a CC weapon since retiring. I own both .45 and 9mm but personally go for weight over velocity. I will say that a person needs to have the proper hand size to handle a double stacked .45. I carried the same Glock 21 on duty and have a Glock 30 that I carry for CC. Never any issues with either weapon.
I like both, Proficient with both. During my service time 1911A1 was my PDW. I also favor the Browning HP. Both are great sidearms. A bit more hefty than other now day carrys. A friend mentioned the weight to me. I told him its nothing once you get used to carrying it. I think its all a matter of personal choice and preference. What ever we carry Be the best we can be with it.
LOVE MY Springfield 1911A1. 5" Barrel, but to carry on body concealed, it has been hard to conceal. I have a Springfield XD 3.8" .45 ACP, 9 / 13 magazines, does that count? Fits like a glove. the 1911 has a 4-pound trigger and even though the trigger is adjustable, I leave it alone. There are extended magazines 8+1 and 10+1. Weight is nearly 3-pounds loaded.
