1911 barrel lengths

I think I know the answer but want to make sure. My brother and I were having this conversation over the weekend.
Full size 1911 pistol has a 5" barrel. Not including a long slide model.
Commander barrel is 4.5"
Officer barrel is 4.0"

I realize there are short barrel variants by different manufacturers. I noticed Ruger's officer is a 3.6" barrel. My question: are there standard barrel lengths for the commander and officer size 1911 pistols?

Don't forget the "long slides" with 7" barrels.

It was AMT that made the Hardballer. Picture the Terminator saying "Are you Sarah Connor?" while holding one equipped with the huge early laser. Great movie scene.

They did, and there are a number of manufacturers making them right now. Dan Wesson, Remington, Kimber, Springfield Armory just to name a few.

OP, also keep in mind that the frame size can be different as well. The 1911 government (5”) and commander share frame, but the commander frame is aluminum. If it is a steel frame it’s a combat commander. Meanwhile, an officer’s frame is aluminum and is smaller than the government/commander size, figure you lose one round in the magazine. Of course in today’s market with all the different makers coming up with new edc models, there is now quite a bit of variation to those terms and not all models are true to form 1911’s. So, more than you wanted OP, but point is there is more than just barrel length differences in the “standard” government/commander/officer models.

6 inch 1911s make special sense in 10mm.

Mark204, My mistake, the AMT Long Slide had a 7" barrel. I used to own two AMT HardBallers. One was a standard 5" and the other was a 7" long slide. Both were stainless steel. Excellent frames and slides but really junk barrels and internal parts. I chronographed both with the same ammo (230gr GI hardball) 850 fps for the 5" and 918 fps for the 7". I sold the Long Slide but kept the 5". It was a clone of a Colt Gold Cup with a Millet "airplane wing" adjustable rear sight, an extended trigger, and a beavertail grip safety. I decided to buy a Kart match grade barrel and bushing then I replaced the hammer, sear, disconnector, 3-finger spring, mainspring housing, extended thumb safety, and extended slide lock with high quality Wilson 1911 parts. I also put a set of Pachmayer wrap around grips with finger grooves. The AMT magazine was pure junk so I bought some stainless Wilson Combat magazines. When I finished, I had a very nice match grade pistol that I used for NRA bullseye matches. I only fired "hard ball" in is and never did have a malfunction of any kind.

Last year my friend from Sioux City stopped by for a visit and ended up taking the AMT home. He had just started shooting bullseye matches and had been using a Colt 1991 (not a 1911 and far from being match grade). Every now and then I get a call from him telling me how he won another match with the AMT.

AMT also made a 7" long slide in a 10mm Auto called a Javelina …. very sought after back in the day.

Hardballer is AMT's 5"
Terminator used AMT's Longslide had a 7" barrel

I don't think AMT ever made a 6" 45 acp , maybe in another caliber but I can only find 4" , 5" , and 7"

The AMT Hardballer was THE FIRST stainless steel 1911 and I bought one.
Still have it sitting next to me right now!

And it's not ATM ...it's Arcadia Machine & Tool - AMT

Nomadic Paladin will become famous soon enoughNomadic Paladin will become famous soon enough
Government = 5"
Commander = 4 1/4"
Colt officer = 3 1/2"
from there they are all over the place
Colt defender = 3"
Smith and Wesson ultra compact = 3.2"
Sig Ultra Compct = 3.3"
Ruger Officer Style = 3.6"
Springfield ROC = 4"
Some Kimber Pro models also 4"

Add in bushingless barrels, full length guide rods, bull barrels and bell barrels and there is no real default configuration other than the original design with a barrel bushing, which many full size (government) models still employ.

Not all officer frames are alloy. The Dan Wesson PMC is one example.

If anyone needs a magazine for an AMT 45 acp the ones from Mec-Gar work great .
During the last few years of production AMT stated using the Mec-Gar's which were a lot better than whomever supplied their old ones .

I won a first place trophy with my AMT in a 45 Only Match , so I kept it .
