Anyone want to educate me on the major differences between the two calibers. Pros and cons etc.

BTW, I already own a 44mag (for the woods) and a Glock 9mm (for concealed carry). Looking for something on the heavier (larger) side in an auto to span the gap if you will.

Well J-Po no one has answered so I will try. First you should understand that the two guns are not really comparable, Do some searching on the web as well.
The 45ACP is a well established sidearm, 230 grain bullet at 830 or so fps.
The 10mm. is a powerful cartridge with a 200 grain bullet at about 1300 fps.
There are 1911's engineered for he 10mm. Colt's Delta Elite for one. Glock also has a 10mm and so does EAA. My gun is a EAA Elite Match.
A weaker version of the 10mm is the 40 S&W (short and weak!).
Plenty of folks use the 45 acp as a concealed carry gun. I am not aware of anyone who uses a 10mm, but I'm sure someone will chime in!
What is a 10mm useful for? Dunno! Hunting for one. A hunting sidearm (in semi auto) for another. The 10mm is also available in a revolver by S&W if that turns your fancy.
As you have noted, the 10mm is generally available in a larger frame gun.
I really like the cartridge!
Incidentally, the 10mm uses 40 cal bullets so these are relatively inexpensive. Brass for the 10mm is expensive (compared with the 45 ACP) so you have to watch that!

I doubt that anyone would notice a difference between the 45acp and 40S&W .I certainly haven't.
The 10mm is a different thing.Too powerful for SD .It approaches the 41 mag and is suitable for hunting things like deer.

I'm a .45 fan but I'd go with the 10 mm on this one. The .45 is a good cartridge but I wouldn't recommend it as a hunting round. Yes, it has taken deer but. The 10 can be loaded for a defensive sidearm, target gun or full power load. If you reload you can even load it as a reduced .40 target load.

I carry a Dan Wesson CBOB in 10mm for CCW. I also carry it when hunting hogs. Great round! The 175gr Silvertips are hard to beat.

And w/ a 45 ACP you can walk into most shops selling ammo and find a box in this caliber. 10 mm is going to be hard to find. It's like the difference between 30-06 and finding ammo for a Mosin Nagant pistol.

Sadly the 10mm and the 41 Mag share the same fate. They are good cartridges, but where is the ammo???

Also most current 10MM is a 180 at @ 1030.

The 1200 to 1300fps stuff proved very hard on the pistol.

With the 45 ACP, standard ammo in 185 to 230gr, the 1911 will shoot nearly forever,and with +P or +P+ loads, you can easily equal 10mm ballistics. And find ammo.

I am a 1911 Freek, but...
In the field, I MUCH prefer a revolver, in 44 mag....

I know Ted Nugent pretty much carrys only a glock model 20 in 10mm...........

Gotta love uncle Ted

You can buy loaded ammo for the 10mm from Georgia Arms.

It shoots "flat". So if shooting at anything over fifty yards is important to you get a 10mm. If not? I would stick with a .45 ACP as shot recovery is quicker. And under fifty yards it is that which counts!

Thanks for all the opinions! It really gives me an idea what each caliber is about. Sounds like the 45acp is more of what I am looking for since I tend to be practical to say the least (current rifles are .270,.30-30, and .30-06). I like the whole "easy to find ammo" deal. With that said, the 10mm comes in a glock and I am used to that as well as being a good back up weapon during backpack hunting and a bit easier to carry (and shoot) than the 44mag. As would the .45, though a bit weaker. The 1911 in .45, with it's history and reliability, and ease of customization earns it points as well. I am now more confused than when I started. Leaning toward the .45 in a 1911 or glock though to fill the gap. Thanks for all of your input everybody. More than happy to read any other views on the two.

I like the 10mm round, own a coupel diff guns, shot the G20 a lot, it's a good round, but all that much better than a 45acp, not really.
The 45ACP is a well established sidearm, 230 grain bullet at 830 or so fps.

The comparison of handloaded 10mm w/ factory 45acp is noty quite a fair one. You'll be pushing the 10mm really hard to get 1200fps w/ a 200gr bullet. You can drive a 230gr JHP @ 1000fps w/o bending anything & 200gr to 1100fps in the 45acp. Neither makes a good trail gun IMO, not versitile enough, the 44mag wins that one. Maybe the best part of a G20 0r G29 is w/ extra bbls you get 3 guns in one; 357sig, 40 & 10mm.

One of the main advantages of the .45ACP is that it is a military round and, therefore ubiquitous. Another advantage is that it makes a slightly bigger hole. The advantages of the 10mm are a slightly better SD and a little more magazine capacity. Neither is really a hunting cartridge but I would imagine a deer shot with one or the other would react about the same. If you have a modern revolver you can get some pretty stiff loads for it by shooting Auto-Rim, +P, and Super. In a good auto you can shoot +P and, by changing some springs, you can shoot 45 Super.

From Buffalo Bore for example:

.45 ACP +P Ammo - 185 gr. J.H.P. (1,150 fps/M.E. 543 ft. lbs.)
.45 ACP +P Ammo - 200 gr. J.H.P. (1,050 fps/M.E. 490 ft. lbs.)
.45 ACP +P Ammo - 255 gr. Hard Cast FN (925 fps/M.E. 484 ft. lbs.)

.45 Super Ammo - 185 gr. J.H.P.(1,300fps/M.E.694 ft.lbs.)
.45 Super Ammo - 200 gr. J.H.P.(1,200fps/M.E.639 ft.lbs.)
.45 Super Ammo - 255 gr. Hard Cast FN (1,075fps/M.E. 654 ft.lbs.)

.45 Auto Rim +P Ammo - 200 gr. Jacketed Hollow Point (1,200 fps/ M.E. 639 ft. lbs.)
.45 Auto Rim +P Ammo - 255 gr. H.C. F.N. (1,000 fps/ M.E. 566 ft. lbs)


For comparison sake, here are Buffalo Bore's offerings for 10mm:

Heavy 10mm Ammo - 220 gr. Hard Cast - FN (1,200 fps/ME 703 ft. lbs.)
Heavy 10mm Ammo - 200 gr. F.M.J. (1,200fps/M.E. 639 ft.lbs.)
Heavy 10mm Ammo - 180 gr. Jacketed Hollow Point - J.H.P. (1,350fps/M.E. 728 ft. lbs.)

Compare the 10mm 180gr @1350fps with the .45 Super 185gr @1300fps and you can see that with handloads or pushed to the limits of safe pressures they really aren't very different at all. I purchased one of the .45 loads above for a trip to Alaska "just in case" but never used them.

Standard loads out of the .45ACP are very easy shooting, accurate, and proven performers. I find the 10mm, even with standard loads, takes a little more effort to keep on target because of the recoil. The two are so close it boils down to personal preference. My preference for carry is the .45ACP in a 1911 (1991). I practice with MagTech but qualify with and carry issue Winchester hollowpoint rounds.

I own both calibers and regarding the availability of ammo the .45acp is hands down the winner. Having said that, the 10mm is not as difficult to find as some would make it seem (thanks to the internet and a little fore- thought). I just bought my 10mm and quickly learning to love it!

Some of the outfitters and horseback riders here in Idaho are moving to the Glock 10MM.

They make an interesting case for the full sized Glock 20. Weight empty is 28 oz and 39 oz loaded with 15 rounds. I think you can get a magazine extension to add another 2 rounds if 15 isn't enough. With Buffalo Bore or other high end ammo that is a fistfull of power in a light package for the critters that could harm ya.

Another option would be an old model Ruger Vaquero either in 44 mag or the 45 Colt turned into the 45 Mag. Empty it runs 45 oz and I don't know what it would run with 6 rounds. Granted more power per pop but a lot more pops per pound with the Glock. I like the option of the additional rounds with the Glock.

I have some old Model Vaqueros in 45Colt and 44 mag and they are heavy to carry even in a cross draw holster.


Hmmmmmmmm......... now I'm think that I might need a 10MM.

J-Po

As much as I like the 1911, I was "forced" to carry a 9mm for several years, I chose the Glock over the SIG or the Baretta.

The Glocks I used were very rugged and reliable, and I shot them a bunch.

If you like the Glock then a Glock in 45 ACP would not be a bad choice.

I would not hesitate to shoot a little Buffalo Bore +P 45 ACP in a 1911 or a Glock.

If I carry a 1911, even if it is my LW Commander [aluminium frame] in bear country, I carry Buffalo Bore +P 230gr FP.

I always carry some Speer 45 ACP shotshells to shoot grouse with as well.

I'm not a big Glock fan, but I could make an exception for the Glock 20.

Amen....

If it's for constant carry and/or concealed carry, and you like Glocks, there are two smaller Glocks, models 30 and 36 I believe.
