I'm trying to evaluate a Colt Officers ACP series 80 for a friend. Took it out and shot around 75 rds ball, factory and my handloads. Definitely not a tack driver but grouped ok out to 15 yrds.
Problem I had was some brass I picked up was really tore up on the case mouth (see pics), but the gun never stopped running, ie: never had to clear any jams! What would cause this? Looks like the slide caught the brass against the chamber and smashed it, but like I said it went into battery every time. Is it too strong of a recoil spring? Light? The gun is loose and well worn. Any Ideas? I know I could have posted in 1911 forum, but I need instant gratification! 
Thanks |

Quoted:
Adjust extractor tension and install an ejector with a short nose. Is this a long one? It is longer than the one on my Kimber. Can it be filed down? Does the extractor need to have less or more tension? After looking closer at the brass, there are some marks on the rim also. It must be trapping the brass for a shot time then flinging it out and continuing into battery. Almost all the brass out of it has at least some marks on the case mouth. Only found a few that were as tore up as in the pic. Thanks for the info.

Unless it's your picture, it looks like the ejector has been replaced. It should be stainless steel and the picture looks blued.
Here's some things that could be causing the problem. 1. The gun needs a new recoil spring. Either the spring(s) are worn out, or someone installed too strong a spring. Either too strong or too weak can cause trouble. Original Colt was two recoil springs, one inside the other. Now you buy a new single spring from Wolff Gun Springs. These ultra-short guns are hard on springs and they need to be replaced more often. You need a 22 to 24 pound Officer's length spring. The 24 pound is for hotter loads. 2. The extractor needs to be tuned. Either take it to a good gunsmith or look online for instructions on how to tune it. This is the most probable cause of the damage to the brass. Here's Brownell's instructions on tuning: http://www.brownells.com/.aspx/lid=10261/learn/1911_Auto_Extractor_Adjustment 3. The long ejector is standard on the Officer's so it shouldn't need replacing or shortening. 4. Try different ammo. |
