I keep reading about problems with plugs blowing out of models 1991A1, 1911 and that style of pistol. Is this a real common problem? Does the plug just shoot out of the gun when it fails? Is the aluminum guns more prone to this problem than steel ones? You info is appreciated.
 
I have read of a few cases where the barrel bushing failed (broke),causing the spring and plug, to go flying. Doesn't seem too common, but it can happen.

Since all the parts involved are in the steel slide, it doesn't have anything to do with whether or not the frame is aluminum.
 
I have seen about 2-3 bushing failures which caused the plug to leave the slide. But, that was minor compaired to the damage that could of occured.
The older Colt bushings, that have the "four fingers" for tighting up the barrel lock-up when in battery, seem to be the ones that fail. I've switched my older Colt 80's bushing over to a after market "solid" one. No problems and it works just fine.

Of my three 1911 types and about 8,000 rds fired I've never lost a plug like that. I even mave a MKIV with the dreaded collet bushing and find that with the factory barrel its very accurate and completely reliable.

In the stupid 1911 tricks dept. you can always use a piece of empty .45 brass as the plug if the original is gone.
 
The only recoil spring plugs I've ever heard of "blowing out" were on the compact Officer's ACP. They do not use the same bushing/recoil spring plug set up as is used on a 1911 or Commander and the tit on the plug can shear off.
 
I've heard of the those old, spring-loaded recoil "buffers" punching through stock plugs, but I've never heard of a plug failing; what's to fail?
