I don't know about that. I'm sure they would be just a bad a shot with 6 rounds as with 15, you can just do a lot more damage with 15 errant rounds. If you don't practice regularly, in a stress situation with the adrenaline flowing you will have poor shooting discipline regardless of how man rounds are in the magazine or cylinder.
“I don’t know about that”.
Well I do. Read the news sometime, check out the body cam videos. The problem is they aren’t generally good shots.
