    Colt 1911A1 Series 70 45 ACP

    Hi all: a guy on another forum has a Series 70 1911A1 for sale. He bought it from the original owner, an older gentleman. The pistol has a National Match barrel, and he had to replace the
    collet because one of the points broke off. Does anyone know if some of these pistols came from the factory with National Match barrels? Also, what would cause the collet to fail? I would
    like to get this Colt 1911A1 if the price is right, but I also don't want to buy a gun with problems. The seller says it shoots great. What say you? Thanks in advance!

    The collet bushings were supposed to improve accuracy by tightening up around the barrel when the pistol was in battery. The problem was not with the design itself but Colt's quality control. If the slide ID was too small the fingers of the bushing would buckle under the pressure and eventually break. Also if the front of the slide wasn't machined perfectly square it would stress the bushing as well. But as long as the slide was machined to proper specs the bushing usually worked fine and lasted a long time. National Match barrels usually have a narrow chamber hood dimension so I don't know what you've actually got in that pistol. Have him take pictures of the ejection port with the barrel installed and see if there is a large gap on the side of the hood. If there is then Colt didn't install that barrel.

    Gold Cups came with a match barrel but normal production examples did not. There's always a chance that a match barrel slipped into the production line or some special order from a distributor, but normally a production line pistol would only have received a standard grade barrel...and even Colt's standard barrels were very good.

    After so many years it's difficult to determine what may have been changed on the gun by someone. Records can be lost...memories fade...anything.

    I would suspect that the barrel and bushing were replaced at some point,so keep that in mind when pricing it

    One lesson I learned here was always buy the gun, not the story.
