I'm not with you on this, Cayle. First off, I carry a 1911 every day. I have a .40cal as a back-up gun in 3 different brands. Glock (cough, spit cough! LOL), H&K and S&W. The platform you shoot a .40cal from makes a difference. A big difference, IMO. I don't know what y'all had but it might matter.

I also have a .380 as a tertiary back-up. Yes, that is 3 pistols most of the time. My .380 in one platform my Wife HATES! It is very lightweight and flips a good bit. The trigger is what she doesn't like. She know in a shit-hits-the-fan moment she can deal with the trigger and can mange the flip. With another pistol in .380 the flip is pretty much the same but she LIKES the trigger. So that's what she like. She has very similar feelings about my 3 .40cal pistols.

Actual ammo makes a difference as well. Not really a caliber issue, and not even so much an ergonomic deal. Just the feel. Obviously y'all have to do what you feel to be comfortable and safe. I just hate to see a caliber get a bad rap for what might be the pistol's fault.

Just picked up one of each. One for me, one for my daughter.

The reason there is a controversy is because trauma surgeons cannot tell the difference between a 9 mm (.358), .40, or a .45 gunshot wound. The terminal ballistics have virtually no difference. The controversy goes further that short of a shot through the cranium, the sealed, pressurized cavity in a human skull, a handgun is incapable of inducing hydrostatic shock. And because anyone who graduated 8th grade is expected to know for each action there is an equal and opposite reaction, handguns have no comparable “stopping power.” It is a myth, and no amount of science with prove otherwise. Therefore, it it only logical to say that since terminal ballistics, for all intents and purposes are virtually identical, it is best to employ a round that offers the greatest magazine capacity and least perceived recoil.

WO1 (Join to see) Muzzle Energy is pretty comparable as well. The .45 is heavier, but moving significantly slower than 9mm

MSgt Cayle Harris - I don't know how many times I've heard this, but in comparable ammo, it's simply not true. Using Hornady's Critical Duty as an example, the 45 ACP+P produces 464 fp at the muzzle, the 9mm*P produced 369 fp, and the 40 S&W produces 396. The a 20% drop for the 9mm and 15% for the 40 S&W, both producing smaller wound channels. I'll have to disagree with the W01 Gray too. I've hunted with handguns and pistol caliber carbines for a long time and you certainly can tell the entry wound from a 44 magnum or from a 357 magnum, which are comparable in size to the 45 and 9mm. All three of these rounds will get the job done, so handgun choice is whatever you like personally, but ballistically the only thing that takes out the 45ACP is the 10mm. I'm not sure the 10mm is suitable for a duty gun unless your beat had large bears.
