Life expectancy of 1911 barrel

What is the average life expectancy of a 1911 barrel, through which FMJ ammo is shot?

Average? As in a barrel in an average off the shelf 1911?

Probably about 5,000 rounds. Then the lower lugs will break off or the radial lugs will be rounded off.

Properly fit?

About 35,000.

Seen a few name brands go over 50K including Kart, Wilson and Nowlin.

I think Hilton Yam wrote on 10-8 that he has seen barrels with somehwere around 100K rounds through them and they functioned fine. He wrote about how there was very little rifling left but it was enough to get the job done. Basically by the time you wear out the barrel you will probably have to replace the high wear small parts a lot sooner.

A buddy has over 10k rounds through his Norinco 1911.

I have over 6k rounds through my Fusion.

Neither has had any issues.

One of the barrels I have seen was a Wilson that had 80K through it. Still held accuracy but was flirting with power factor.

I have a Norinco M1911A1 circa 1993 in .45 ACP. It's unmodified excapt ofr grips, sights and a long trigger and I've done nothing special to it but wash it, fuel it, and change the oil. There have to be at least 25k rounds through it. It runs fine, goes bang every time, and is more accurate than I am capable of without a bench rest. If a crappy "commie" 1911 can go that long, I'm sure a good stout American can go as long or longer.

Actually, that Norinco is built to last longer than a good number of "American" 1911s that cost double if not tripple the price.

Yeah, I know. Didn't want to invoke the flame gods.

I had a tad under 10,000 through my springfield loaded before i had a new barrel fitted. I only did that because i had to completely overhauled by Hoag.

It was still very accurate and probably more accurate than i could shoot myself.

The same Jim Hoag mention above told me any decent 1911 should go 50,000 rounds without much attention (except for cleaning and lubrication) or parts breakage. At around that point they start loosing their accuracy edge (he was talking match accuracy) but will still function fine up to 100,000. Some parts breakage is not unusual, but that depends on the quality of the parts to begin with.

I've been at this for over 40 years and I've never seen a worn out (rifling) 45 ACP barrel. In fact I only know a very few people who manage to get to that 50,000 round point. Most sell their guns for something different long before that.

The oldest 1911 I have is this one:

1911 Forums

It is a 1959 vintage Colt Government Model that was used but not abused when I bought it. I had it lightly customized, including a Nowlin barrel, and used it for competition through out the 1990s and still shoot it today. At one point I started keeping track of the number of rounds (reloads) I had fired through it. When I got to 20,000 without a weapon related malfunction I quit counting...and that was over 5 years ago.

YMMV,
Dave
