So you cant chamber a round and be ready 2 seconds before needed at times, ever?
It took me 2 seconds at the MOST. I had my daugher say "Go" or "Boom" and could draw my holster, chamber it AND point it on average of 1-1.5 seconds. 2 being the slowest and under 1 second the quickest. But there are alot of other factors to vary in. I was calm, expecting it, I had my wits about me and both hands working.
One thing I need to work on, is stepping to the side instead of back...I noticed that. Stepping back, I stay in the line of fire, I should side step.
