Two inches is what I train to perform. Don’t always get it but I can hit in regularly on the range in no stress and about 50/50 on speed drills. I stress 2” because most people under stress will increase that radius 2x or even 3x. I figure 6” in close quarters battle will be good enough to hit the heart or head.
No worries. Two inch groups at 10 - 12 feet, no stress *SHOULD* be doable ... with two hands, ‘rapid’ fire.
See you at the range.
