DQed at Circleville yesterday on the next to last stage - at the very very can't be closer to the end. I'll set it up - Had finished the COF. I was on one knee as the last 3 poppers were through a low port - not especially low, but low for me. RO gave usual commands to unload, show empty, drop hammer, reholster - here's where the problem was and he was doing his best to make me understand to STAND UP first. In the position I was in, I ended up sweeping my thigh, but worse - I broke the 180 trying to get holstered. Sorry guys. A couple of the guys seemed more disappointed than me - that made me feel better. But I learned from this. And if the 180 is going to be broken, I'm glad the gun was clear - with no doubt. I know 100% what I did wrong and what I should practice to help with transitions from standing to kneeling. Stayed to see the squad shoot the last stage and paste.
