I don't shoot my M1911's unless they are heavily lubricated. Bullseye shooters told me the elbow is the drip point for oil. So I lube the heck out of my pistols.
Just today at the range I met a Vietnam/Iraqi veteran. His Beretta M92 was bone dry. I told him to lubricate the thing, he told me that the Army said not to, oil attracts dirt. His pistol functioned fine.
Another time, another Vietnam Veteran, his Rock Island 1911 was malfunctioning, it was bone dry. After I lubed the thing with motor oil, it started working again. He had been told in the Army to run them dry, they had been told that oil attracts dirt.
Well I ain't dropping in no combat zone.
A guy with a LLama 1911, his gun was bone dry and it was malfunctioning. A little bit of motor oil and it starting functioning correctly.
