So here I am, putting on my shoulder holster and the snap I thought was secured wasn't as secure as I believed it was and there goes my gun, four and a half feet down onto a steel floor.
Even though the gun hit the floor with enough force to force the slide back despite the thumb safety (the thumb safety literally slid OVER the slide pushing the thumb safety out slightly, but not enough to render it useless), the thumb safety never disengaged and, of course, the hammer never fell and the gun did not fire.
There is a small scar now where the thumb safety scratched against the slide while the slide was forced beneath it....
Bad picture but it was taken with my web cam.
After taking down the entire gun to the main-spring housing nothing but that scratch was found to have been damaged.
I've never had such a "drop test" before and even without a firing pin block nothing happened (as you would expect and desire).
I'm very happy with my gun. It has withstood the test of Limatunes and passed!
