Hey folks, now I know why I took the end off the the two piece mag extension. The one that comes with two screws. Because of the whacked weather here in NJ this winter (?) I was out and about today without a jacket. So I was wearing an undershirt with my polo outer while carrying IWB. When I got home, as I was pulling the gun out to put it in the GunVault, the extension top piece caught and hooked into the thin undershirt. Caught it solid, too. Couldn't clear the holster and even after tearing a hole on the next pull, still couldn't clear the holster with my G19C. I had already took that top piece off my extended mag release on my G36 and sanded the edges smooth. Good thing I did because I carry the G36 95% of the time. Well, I can see what's on my itinerary for tomorrow.
