Can anyone tell me what are the most common cause of "stove piping". I have a Colt Gold Cup NM Series 70 with a Wilson barrel and comp. I also have the solid guide rod installed. Any information would be appreciated. Thanks.

what type of magazines, how new are they, and how many have you tried in that gun?

The main cause of stovepiping is a too heavy recoil spring, which increases the speed of the slide foward, which catches the empty brass before it can clear the ejection port.

Wouldn't that be considered a failure to eject? I have always considered a stove pipe for a 1911 is when the nose of a live round is caught outside the breach, resembling a stove pipe.

Either way, weakest link in the 1911 is the magazines. Try different mags, have someone check your feed lips on the mags you have now, if they are bent out of spec, would cause the problem you are describing.

i was getting failures to eject, caught inline with the bore though not straight up like a traditional stove pipe.  the wilson chamber cleaning tool solved it.  it was happening in multiple weapons.

from Bill Wilson's book "1911 Auto Maintenance Manual"

Possible Cause :
Load too light for the recoil spring, recoil spring too heavy for load, extractor tension too light, worn extractor hook, loose or damaged ejector, loose grip when firing.

Thanks to all of you who responded. The magazines are Chip McCormik and they worked fine in my friends .45. I'm going to lean towards the recoil spring for the moment. I'll let you know how it turns out. Time to visit Wolff Springs website.

Yeah, I was going to say limp-wristing.  But who knows.....
