Colt 1911 production date using serial number
This is my first post and great to have other shooters with knowledge to answer some tuff questions. This is my first Colt, it is a Gold Cup National Match MK/IV / Series 70 serial #70N23060. I would like to know what year this particular model was produced and what to expect from it (problem wise)
if any. It is just as it came from the factory, with the exception of being shoot, Lord knows how many times! Gun is clean and I would rate it at 90% when I get it cleaned up, and I am very anul about my weapons. I have about $800.00 in it counting transfer fees and a box of MagTec 230 grn FMJ. Thanks in advance. |

According to R. L. Wilson's little handbook, your gun was made in 1975.

Since it is a Gold Cup, reliability is probably not a factor, but if the gun will be used other than on the range, and it still has the 70 Series collet bushing, I suggest replacing it with a standard bushing.

IIRC Gold Cups come with 12 lb recoil springs, you should make sure you have at least a 16 lb spring installed, I hae a 18 lb spring in my own for hard ball.

If it's been shot a lot and the collet bushing is intact, it's probably going to stay intact. The issue appears to have been slight errors in machining on some guns that resulted in stressing and breaking the bushing, so the problem isn't the bushing per se, but how your gun treats its bushing.
I'd be more concerned with the rear sight. The Elliason has a reputation for breaking various parts, most often the roll pin that goes through the slide at the front of the sight. Some have reported good results from replacing the roll pin with a solid one, but others have had problems with the harder pin then wearing the hole in the slide. Compressing a sliver of shok-buff under the sight body, so the sight isn't bouncing off the stops with each shot, should help it last. I had a Series 80 Gold Cup slide on a gun, and within a few hundred rounds all the pins and adjustment detents broke. I had it loctited in place. If your gun has been shot a lot, and the sight is still stuck on and adjusts properly, then someone may have done some preventive maintenance already. If the gun has seen a diet of softball loads, that would have made the sight's life easier. |

Colt finished 1971 with serial number 70N2001 and finished year 1972 with serial number 70N06201. Yours was made after they turned off the lights in 1971 and before the end of 1972.
