Carried a 1911A1 as an MP. They were junk, but they worked. Never been a fan though. I don't care for carrying any pistol that requires deactivation of a safety lever to fire (or carry cocked and locked). But I know how a lot of people are about polymer pistols. To each his own.
As for...
Comparing the 1911-style pistol to the Glock-style pistol ("striker") is like comparing apples to oranges.
Training is key.
Neither are safe in the hands of an idiot. Both are safe in the hands of a competent, safety-conscious person.
