I agree!
People should aspire for excellence in everything they do.
I'm not happy if all five rounds don't go into an inch at ten yards consistently, standing/unsupported. Then again, at age 61 my eyes aren't what they used to be.
That ratio means 2 1/2" group @ 25 yards, 3" at 30 yards, 10" at 100. Decent shooting, but surely not exceptional.
To the OP, I WOULD recommend two things:
1. Lots of bench shooting until your grip and trigger mechanics are perfect, then transfer it carefully to your unsupported shooting.
2. Do a lot of shooting with a chamber or two unloaded. Spin the cylinder until there's no way you know when it won't fire. Do it over and over until you don't milk the gun or flinch or blink with the gun fails to go off. Then, you'll see your offhand shooting REALLY tighten up. You should see the muzzle flash with each shot, if not, you aren't shooting very well that day!!! LOL
