A bunch of folks in this thread firmly (yet IMHO, mistakenly) believe that every shot they'll fire in a gunfight is gonna' be a center mass hit. Capacity is also effected by...misses :yup:
I went middle of the road, PPQ in 40. 12+1 capacity, 165 or 180 grain. I shoot it very well after only a few days range time with (more to come) and I the recoil is hardly as bad as some people make it out to be.
Bear in mind you can always carry a second clip...
"Capacity" with MY "caliber" of choice....G19....15+1 :smile:
Current 9mm jhp ammo closely approaches the effectiveness of .45acp. I find it easier to get more accurate hits, faster with 9mm.
So, after 30 yrs. of pistol shooting I'll choose the hi cap 9mm. :)
I'd go capacity. I own two 9mm find and they are cheaper to shoot at the range (I don't shoot reloads.), Better follow up shots due to reduced recoil, and obviously higher capacity. (Mainly easier for range time as I don't foresee myself ever getting into any extended gunfights.)
Caliber, if you need more than 10 shots (or even 6) to stop your attacker then you're either fending off a gang, or a terrible shot.
I'd rather a .357 magnum revolver.
.40 and good shot placement.
More bullets = better chance at good shot placement IMHO.
I like to select by time of day and where I am going. Just going a couple of miles to wally-world I would travel light with my little 32 auto (its a good neighborhood). The north side of town during daylight my 9 with an extra clip. If I'm stupid enough to go to the north side at night, 45 backed up by a 40 backed up by the 32.
Today's ammo performance in all calibers made for SD is pretty good all around, designed for that weight, speed, caliber etc. so I think I am going to have to say I'd probably go with capacity.
I used to think I could fend off the world with just my .45 and 7+1. Nowadays and after reading a lot of experts and talking to some too I believe capacity trumps caliber. That's why I went back to a double stack .40 (9mm just as good). I want double digit rounds, end of discussion.
The main reason is, in a really, really bad situation, I can't say that I'll be taking my time and aiming all that well. Seems to me the more rounds, the better. Suppressive fire is a wonderful thing.
In handguns of similar size, assuming all other factors meet my minimum requirements (reliability, power for the purpose, accuracy, concealability, cost), then I'd have to say: capacity.
ie, Similarly-sized lever-action rifle in .44mag (10rd) vs .30-30 (6rd) for bear or deer, I'd prefer the 10rd .44mag rifle every time, but for reasons of capacity. Same with a similarly-sized 9mm vs .40S&W vs .45ACP pistol, or a .357mag or .44mag revolver, in which I'd prefer the greater capacity.
