Yep, I even know of a ND from a Glock by the department armorer.
The round went through the wall and into the CIB (detective's) office area. Luckily there was no one in that office area at the time. The building was once an old hospital and the walls were lath and plaster with wire mesh, so they had a lot of influence on slowing down the .40 caliber round, so most of the energy had been spent before it hit the wall on the far side of the room and didn't penetrate. Had it passed through the second wall, the next office it would have entered belonged to the city manager, and he WAS at his desk.

While I understand some concern as psychologically no one wants to stare down a gun barrel that they are not in control of, a properly operating holstered 1911 in Condition 1 does not present any safety problem. It is no different than having your 1911 IWB holstered in the same condition.
