people in the know say,
80% of people shot with a pistol live.....
80% of people shot with a rifle or shotgun die....
i forget who said it but it was someone in law enforcement.

I carry a 9mm everyday with one of the modern "wonder bullets" loaded in it. Would I pick something different if I had the choice? Yep. Bottom line though is that I don't have a choice and I feel confident in what I do have. I do also agree that marksmanship thing is paramount. I have been on a two way firing range and some degree of marksmanship will inevitably go out the window when that situation does arise.
TinkerBell, on a two way range, it ain't whether or not they die after they are shot, it is how quickly they stop trying to kill you! Neither cops nor CCW holders shoot, nor are legally entitled to shoot, to kill. They shoot to put an abrupt end to behaviour they deem grievously dangerous to themselves, or those in their charge.. The avenues to do so open to any handgun are limited. A CNS hit in the thorax, a brain shot between the eyes or ear hole, and hopefully, the Hollywood effect, wherein folks receiving minor gunshot wounds believe they must react dramatically and become immediately incapacitated. Any will do just fine if he is shooting at you! Standing about waiting for an armed, aggressive assailant to bleed out, which is how most bullet wounds cause death, is a poor option.
If we examine the daily routine of a patrol officer or an investigator, it is plain to see that lugging a short-barreled 12 gauge in and out of his car, in and out of your apartment, up and down on the grass and gravel in scuffles with his clientele is highly unsatisfactory. Indeed, a slung long gun would be a distinct disadvantage in physical confrontations with wrong-doers. A good secure holster keeps popular issue service guns on the hip, out of the hands of would be wrestlemania stars and their girlfriends!
So, choice of a caliber matters. Capacity not so much, since if it ain't solved in the first couple of rounds, it likely won't be solved until after the first reload. Choice of bullet matters, in the off chance you get a good hit and the bullet performs properly, you likely win. If you did so quickly enough that the bad guy didn't land a fatal blow first.
If you did have a choice, what would you choose? Just curious.
An often quoted statistic which bears a considerable amount of truth for civilian and police combat encounters in my observations and experience..."3-5 rounds, in 3-5 seconds, at 3-5 yards". High capacity is nice but top notch terminal performance for each round is critical. For various reasons, you may not get many into your target, so choose your projectile carefully.
LEGAL in canada is 10rds regardless of caliber in handgun..... so i go by legal......
POSSIBLE is me getting nekid with 10 penthouse models simultaneously, highly improbable but possible.......
Software is more important than hardware and at bad breath distance, good shot placement isn't guaranteed. PCP and bath oils has caused many cops to switch away from 9mm if they could under Dept. policy.
If one shoots a 9mm more accurately with the right ammo than they do with a .40 or .45., the 9mm is what they should carry. Just remember at close up arms length, it may not stop the threat as quickly with poor placement. Many women agents and women officers aren't comfortable with bigger calibers and don't shoot them well and are problematic during qualification time as are some men.
The previous FBI concept was that a bigger caliber than the 9mm was better but also wanted to keep some form of high capacity thus the 10s and .40s.
I suspect many agents don't shoot the .40 well and expense too is a factor, so with improved ammo these days coupled with being able to control a 9mm, it's their new concept.
