I fell twice. First time was running right at a wall to a port and slipped when I got there and fell back and on my ass. Gun was up and straight down range. That was an area7 match.
The next one was at a regional IDPA match. Got up from a seated position and just plain tripped over my own feet. Went down on my hands and knees to catch myself. Didn’t loose control of the gun and had finger outside of the triggerguard. I was all scrapped up on my strong hand knuckles and knees.
I think if you have good muzzle control, you can keep the gun pointed down range, however, I haven’t fallen bad enough to where my arms have gone flialing all over. I know people that have done that. One guy slipped on ice, the other stepped on his upright magazine. So I don’t believe you can practice falling. You just don’t know how it will happen. Just don’t shoot anyone!
