I carried a 1911 for many years. I love the gun. Love Glocks too. Just the idea of a cocked pistol pointed at my femoral artery makes me uncomfortable.
Even with a 1911, the grip safety doesn't block the hammer, only the movement of the trigger. The thumb safety blocks the sear and, the firing pin safety (on an 80 series) blocks the firing pin. So, safety wise, its about the same as a Glock. The gun is under tension all the time. If parts break, the gun can fire. On a DA, DAO, DAK HKP7 etc, if parts break, it won't fire.
I'm ok with a crease in my butt cheek if everything were to go wrong, so, I'll keep carrying them and, I like them all.
I used to carry a Bauer (Baby Browning clone) as a last ditch pocket gun. But, on those, the safety blocks the trigger. If the striker slips off the sear, or, something shears off, it will fire, there is not even a firing pin safety. When I realized that, I carried it safety off, chamber empty. Not the best deal if something needs shooting in a hurry.
Its a quirk of mine. Lots of people carry them that way all the time. I'm just not personally comfortable with it.
