Sunday was range day and I brought a couple of 1911's with me for someone who doesn't own handguns (thanks Trudeau).
Stock Ruger SR1911...ran like a champ, as always.
Norinco 1911 Commander...*the issue
I was also shooting a new cartridge for me. Cheap-ish Blazer aluminum cased ammo.
The Commander internally is Nighthawk aside from the stock chinese barrel and link. While I don't shoot this gun often, I've had it for years and never had an issue after I fixed all the Nighthawk fitment bugs. It's been running like a champ for at least 10 years, maybe 15.
Anyhow, range day it was running fine for 3 or 4 magazines, then a stoppage (fail to feed). Cleared it, fired...stoppage (fail to feed). I looked and the ammo cartridge (230 ball) is stuck on the feed ramp!? The center of the bullet tip is marked where it caught the barrel edge!?
The gun then ran a few more magazines worth no problems, then more stoppages as before and I notice this all happens with the same Chinese original mag. I condemned the magazine. Then the gun started to fail to feed with the other magazines. Not that it needed it, but we oiled it and no difference across now 4 different magazine types.
I then ran the Chinese mag through the Ruger, no problems...it's not the mag after all.
When I run my pinky finger across the feed ramps on both guns, both are as smooth as the other. The only discernible difference is a very slight gap on the Commander between the barrel and frame. Very slight, like only thousands of an inch.
Guys, if this was you, where would you start?
Is it possible that the aluminum cases induces too much friction on each other slowing down the slide?
