Wolfe was complaining the other day about cartridge debates on Facebook, ide tend to agree with him that most of those arguments are totally and completely pointless.

This one keeps me thinking though, why choose 10mm over 45 acp for almost any scenario? 10mm makes a big hole but .45 is bigger, so why 10mm?

I think the .45 has more of the “pause” factor than the 10mm simply because of the lower muzzle velocity.

Maybe because the 10mm is typically double stack ??

Glock 45 is 13 rounds and 10mm is 15

Maybe they can double stack them better in guns other than Glock?

I shoot a 45 and I doubt that a double stack 45 would be as comfortable as a double stack 10mm. Everyone's hands are different though.

I'd pick the 10 just because every Tom, Dick and Harry has a .45.

10mm is basically a 40 magnum if I understand it right

If you have one. Then you don't need the other. Like .270 vs 30/06.
But overall .45 ammo is readily available and cheaper.

Sarge's preference - 45 acp. 230.grain ball.

Glock 45 is 9mm- 17 plus 1.

Velocity and rounds in the magazine

45acp is a 20KPSI cartridge
10mm is a 40KPSI cartridge

you get 3 extra rounds in a 10mm mag than the same length 45 mag
45 tends to stay 2-300 fps lower in velocity than 10mm when you get out of personal defense ammo where things are calibrated to 12-16 inches in gel

so more power more rounds

technically since 10mm was around first , 40S&W is 10mm light

a tech at the FBI brought in his own 10mm to test durring the search for a cartridge that would go >12 and <16 inches in 10% gel test medium because that is what the FBI said it wanted out of the next cartridge

he down loaded 10mm till it fit the box the FBI wanted then contacted S&W about making the cartridge a shorteded 10mm

funny thing is Glock beat S&W to market with it because they had the G17 frames , the G20 slides and barrels so all they had to do was use the 10mm extractor fit to a basically 17 slide with a bigger hole bored in the end and shorten the 10mm magazine to fit the G17 frame

all the tooling was already inhouse just not on the same line.

and the G22 was born
by the way the 45acp Glock was G21
the G19 size 40 was the G23

model numbers are in the order Gustopf got pattents on them

learn how to shoot, train often and put the bullet where it needs to be to render said POS deceased. I can take a 22 LR and wear an SOB out because of my training. I dont need anything huge in regards to caliber. Put the payload where it needs to be. its that freaking simple. If you havent been in combat or in LE and in several firefights, you arent prepared for the situation. you will fall back to the lowest level of training under stress.. If you have lit up several combatants, it is as smooth as silk. deal with them and move on... most of you folks have no idea what it is like to be in that situation. every time it becomes easier. we werent made to kill one another, but when your life or that of another is on the line, you dam well better have trained for it.

I dont wont to be in a postition to need to shoot someone, but, it wont be my first rodeo and I will darn sure deal with it as need be.

I hear redneck jokers talk all the time about taking the life of another person. Until they are in that position. Been there with some and they froze when they should have been kinetic. talk is one thing, being able to act in the face of death is another.

950 fps vs. 1200 is the main thing

bullet placement is the main thing. i take it you have never been in such a situation.

many have their BS takes on this, if you havent been in combat or and active LE on a regional SWAT team, your are talking out of your rear end. You have never been face to face with a combatant and in a direct gunfight. save your BS for another time. Most of you have never been in this situation, I have, many times. Our WW2 vets, Korean Vets, Viet nam vets, and Iraq and Afghanistan vets dam well know. I was in Columbia fighting those turds. I have seen my share of this crap and I stilll cant escape the demons that haunt me. If you havent been in such a situation just stop. Because you have no freaking Idea as to what it is and what it is like. Just stop

220 gr. 10 mm max loads run about 980 fps
230 gr. 45 acp max loads run about 960 fps

Seeing Buffalo Bore advertising 255 grain .45 at 925 fps
10mm 220 grain at 1,200 fps

I've never shot a grizzly but hypothetically even in the scenario where you're shooting a grizzly is the 10mm better? Ide be curious to know how a 255 grain hardcast does in a bear at 925 fps, I imagine it would do some damage.

Modesty is overrated

would prefer the 45 for minnesota communists, 10 mm for bears

Fat and slow still gets the job done.
