For all the shit PRS gets at least there's a 180 rule.
I've never shot any kind of hand gun match so honestly don't know, but I cringed like a mofo at the 5 sec mark.
At the 5 second mark he fires 2 shots and thyen you can see he points the gun to his left because he knows he is moving uprange and sideways. He keeps the muzzle down range.
Also, before someone starts shooting a stage like that I get everybody in the squad back a little further than normal, or in the case of this video, back and to the left. I have been back behind the shooting area but far enough to the side that I could see the muzzle when someone was shooting. The first time it happened I said "oh shit". But in reality pretty much everyone shooting a USPSA match is safer than your average shooter. When new people show up or you are dealing with someone shooting a PCC for the first time the more experienced people will coach them and walk the stage with them and show them how point their gun and position their body so they don't break the 180.
