Hey Robby, imagine seeing down in this neck of the woods! I've shot a dozen WB matches now, (we have two a month) using the 1911 for both rifle and pistol targets, and most guys just drop the mags on the run. We don't always have a table to drop mags, though we do have a table to ground the gun if it's not at the end of the stage.
So far I've not had any problems, and most of the time I shoot in a rock quary, and sometimes in the rain (it's Oregon!)
Good luck, JD
