Is this 1911 barrel serviceable?

I purchased this barrel from an auction, but when I received it I noticed it looks improperly machined. The throat is off, but what I'm really concerned about is the barrel hood.

Can this barrel be fitted safely?

Mine looks the same way. Both sides mate with the hood slot in the slide perfectly.

Oddly enough, with all the messing around with the 1911 I've done in the last 40years, I never happened to notice that assymetry before.

If you wnat to double-check, I have a zipped .pdf file of the complete factory drawings of the 1911 at

http://www.loesch.org/~arviel/1911.zip

It's a little less than 4 meg.

I have seen working barrels with this asymmetry before, but not as pronounced. The hood on my SA 1911 looks perfectly centered, though.

230RN, thank you for those blueprints.

The seller has offered an exchange. I will take him up on the offer and see what happens.
 
Put it in the slide and see if it "mates up".
Then assemble the weapon and see if it locks up.
It might need adjustments or it may be okay.

Let us know what happens.

Also, great drawings of the M1911!
 
You're welcome. There may be extra material on the barrel extension in all three directions to allow for custom fitting.

The underlug looks OK to me. Sometimes these are welded on after machining the barrel, sometimes the whole thing is machined from a single block of steel.

As a possibly interesting side question, mine came with two fired cases in a little envelope marked with the serial number of the gun. I wonder how much good all that super-duper detailed record-keeping does if you change the barrel.

make sure you change out the extractor, ejector and firing pin, then the CSI folks won't have anything to match up. BUT it's best not need to worry about covering one's tracks.
 
What about the breech face?

Good point. The CSI TV shows I had watched got as far as matching the firing pin strikes. I actually don't remember a show examining the extractor pattern on the case. but just assumed it would actually be more "matchable" than the firing pin. The breach face might leave a tell tale mark. I guess one would be best to take a flat file and re flatten it after. That or make sure you just police all your brass. Or toss a couple dozen cases you picked up at the local range to really confuse them. This of course all being hypothetical.

This started YEARS ago when Columbo busted a suspect, after he had swapped out barrels on his auto and hid the offending barrel in a lamp. (a lamp really???? as a wire tube or something) DUDE.. take it and melt it down with a oxy accet torch....
 
All the hoods are at least somewhat off center. I concur with a previous poster, the lugs do not look correct. And the barrel timing should be tested.

The barrel throat is also off some. It shouldn't be asymmetrical like that. But it may run that way. Put a case in the chamber and see how much of the case in front of the extractor groove shows. It shouldn't be more than about .038".
 
Looks Right!

The Blue Print PDF that 230RN has supplied....

Thanks 230RN....thats the Bomb! :cool:

drawing shows 6 degree ! .......... Looks good to me!

Hood is not on centerline and is tilted 6 degree basic...if you had some calipers you could do some measurements!
