Barrel lug and pin
 
Looking at a replacement barrel for my US & S. One that I’m looking at has no lug or pin.

How difficult is it to install a lug and pin?

In looking at lugs, apparently there are different sizes (lengths?). What is the correct link?

I think you mean "link" and pin. Very easy to install, after you insert the pin through the lug and the link, just use a center punch on the side of the lug by the hole to distort the metal enough to keep the pin in place.

Selecting the correct length link is part of the process of fitting a barrel to achieve correct lockup. I've never done it so I am reluctant to advise further except to say that it may be a process of trial and error. I'm sure someone else here will have something to say on the subject.

If memory serves- .278" is original link; but like said above there's 3-4 different lengths. Need fitted to be right.

GI .45 barrels were designed to be a drop in replacement part, there's no fitting or staking of the pin needed.

Never heard of different sizes of original GI barrel links, or are you referring to new commercial parts?
I suggest finding & using original GI parts, they're out there.


I put a NOS HS barrel, link and pin in my 44' Remington Rand. Only thing I certainly noticed after the replacement is the pistol is more accurate than with the worn out barrel

In looking last night, I failed to find the USGI parts. I am sure that as you say "they're out there.", But perhaps the fellows who have all of the Singer 1911A1's are hoarding them???

.278" is the original spec size. There're 3-4 longer sizes (.001" at a time) out there. Main job of the link is to pull barrel down out of slide locking lugs. Dimensional slop sometimes require a longer link. The link is not supposed to push bbl up into lockup; that's the job of the lower lug feet on either side of the link. The Kuhnhausen books explain it very nicely. Usually the .278 works just fine.

Pretty much. The first group is owned by Scott Gahimer, the second by Karl Karash.
