10mm or .45 1911

Depends on what bullet weight your gonna run and if the .45 1911 can handle .45 super. at 185gr and 230gr .45 super and 10mm do about the same power wise but the 10mm does better with any weights below 185gr I think. Both are great rounds and either will serve you well.

I never did think the 1911 was a good platform for the 10mm.

Even Colt had problems with the Delta Elite cracking frames when they tried it years ago.

If you can't get-R-done with a .45?

More muzzle blast, flash, and recoil is not going to help you any.

I'd stick with a quality tried and true model in .45. Unless you've got the funds to gamble, or just really really want the 10mm, then to each his own.

45 ACP.

I favor the 10mm Auto over the .45 for really everything...OTHER than in a 1911.

The Colt 10mm 1911 issue was fixed decades ago. Don't forget the first airplane flight was 120 feet and early rockets blew up at liftoff.

Square cut holes near thin areas of metal was a bad idea before the 10mm showed up. The 10mm actually improved 1911's. My .45 ACP frame came with properly rounded upper corners for the slide stop.

Someone asked Richard Heine about 1911's ability to handle 10mm rounds: http://pistolsmith.com/10mm/4763-question-mr-heinie-regarding-10mm-longevity.html

Mr. Heine's quote: "Mine is the one gun I would never get rid of."

In another thread, he said: "If I could only own one Pistol, it would be a very hard choice, but I believe in the end I would keep the 10 and let the others go.

I've shot real 10mm rounds in my 1911 since 2009. It's looking good so far.

I would stick to a .45 if you want a 1911. The only 10mm 1911 I had was a jamomatic, a Kimber Eclipse.

I'd need a REASON to go 10mm. It would be expensive, and I would generally expect ammo and parts&mags to be a bit harder to come by at times.

If your reason for wanting it is just that you want it, and that's enough to justify the extra for you, go for it. Me, if I wanted to pistol hunt hogs or something, I'd rather have a 45 at home and a 44 in the field, and take my extra expense that way.

To each his own. It's a free country.... at least in places

45ACP and 1911 is like Mom and Apple pie.

OP. never stated

A) What do you want to do with the 1911 wherther 10m or 45 ACP?

B) what other handguns if any do you have?

Me? I've got a 1911 5' 45 as well as a S&W 625 45 ACP

So I'd go for the 10mm but really a CCO format in .45 ACP woud be higher on my short llist.

45.

I already own a bunch of ammo, have the reloading dies, and well...I just love a nice, fat 45.

10 for two reasons:
1- more power, and
2- I have one in 45 already.

I would like a 10mm long-slide one day for hunting and woods carry, but it's a ways down the list.

Simple test
1) Do you reload?
YES----->get a 10mm
NO------>get a .45ACP (then learn to reload, then get a 10mm)

The 1911 works best with either .38 Super, not readily available anymore, and 45 ACP. There is little to no need to look beyond 45 ACP in the 1911 platform.

I have been thru a few 1911s in 45, my Delta Elite isn't going anywhere.

For what's it worth, I'm considering getting out of the 10mm and getting into the 45 and 460 rowland combo. I just don't see the 10mm being notably more effective than a 45 for social purposes. And for the woods, you're just one kit away from being able to send 230 grains as fast as the 10mm can send a 180 grains.

If you are wanting it for just SD and range, I would get the 45. If you want more uses out of it for instance hunting I would go with the 10mm.

Already having two fullsize 1911s, I've long drooled over the prospect of owning a 10mm on the 1911 platform.

However, in all reality, I believe I would actually look more towards a 1911 chambered for the near-nuclear .460 Rowland rather than the 10mm. To this end, I've even looked into some conversion units that would allow me to convert my Series 1 Kimber Classic Custom from .45acp to .460 Rowland.

So all things considered, I think I would either go with a 10mm on a different platform that accommodates double stack (higher capacity) magazines such as the G20 SF or convert what I already have to the .460 Rowland.

I would like to point out though that I personally would not choose to carry either concealed on my own volition. I feel compacts are far better suited for that.
If I were carrying OWB on the trails though, I think a 10mm or .460 Rowland (or even .45acp) would be the cat's meow.

I like my M1911s in .45ACP, though I have been known to go the .38 Super/9mm. route every now and then. I'm really not interested in the 10mm. in the M1911 platform.

If you reload 10mm is not a problem and a fun round to shoot, very flat shooting and better at longer ranges than the .45acp. As a reloader the 10 is very fun to mess with load wise, I also like that you can use one die for two rounds.

10mm is a great round, but in a 1911 you want 45 ACP.

My experience with the 10mm in a Delta Elite, Glock 20 and EAA Witness Elite is the brass flies so far its hard to find half of it. So if you are counting on reloading to keep operating costs down its not likely to happen.

10mm is way more versital than the 45automatic. I have both in 1911 and yes I like shooting the 10mm a lot more. Hand loading is also the way to shoot hot and mild loads in the 10.
