Train all the time Vig, never put the flashlight into the Glock but did one time years ago have to take a mag out of the Glock-19 I was carrying at the time to secure the pistol in a sensative area (yes they made you take it out, clear it, and have the magazine removed, and that was years ago). Policy has changed since then, anyway I left the building on my way to my vehicle, and as I have done a gazilliuon times, inserted the magazine into the mag well, and SLAPPED that pupy home, before releasing the slide and chambering a round. BUT>>>>>>>>>>>>>I did just that once, (Don't laugh) have the mag backwards in my hand, and with the bullets now pointing to the rear of the pistols grip, it went in about half way and got STUCK and I mean STUCK. I had to sheepishly and safely disasemble the slide and using a firm stick I happened to come accross, force the mag back out of the grip. I reasembled the weapon and went on my merry way.
