After 100 years i would think the 1911 manufacturers would have found a way to vent the carbon out of the 1911. I love my 1911's but 2 shots and it looks like a diesel trucks tail pipe. i have used about every ammo i could think of but they are all dirty. My old glock was always clean after 200 rounds down the pipe. It was a quick wipe down some oil and all done. why does the 1911 have such an issue with this vs.say glock or xp45?
