A 4" Smith model 66 followed me home today. I'm normally of the school of thought that says the only room at the inn for a revolver at my place is spelled C-e-n-t-e-n-n-i-a-l..but this thing sort of called my name.
You are a vulnerable soul, but you did fine.
I own a 3" M65 and a 4" M18 .22 Combat Masterpice. I practice in the garage w/ the M18 (closed door) w/ Colibris, drill drill drill out of holster and from tabletop. That, plus lots of dry-fire on snap caps with the M65, has made me quick as can be to get the piece to hand, and I can get the first shot on 2" Shoot'N'See centers at 15 feet (or an 8" at 50 feet at the range) no sights without hesitation virtually every time, and more than 50% of the time weak-handed (left).
You can drill like this w/ revolvers at home safely, but it's hard to do w/ autopistol. Also, I think the revolver is a VERY natural pointer, and is somewhat indifferent to bad initial grip positioning.
Fired DA deliberately, two-handed with sights, the M65 will print 135gr Gold Dots into a very decent 5" in at 25 yards. Short sight radius and long (but smooth) DA pull doesn't help; it can probably do better. But I've never seen the point in "benchresting" a short barreled defensive revolver in SA mode.
With 33% greater sight radius and shooting SA, you should do WAY better. My M18 goes under 2.5" at 25 yd. Enjoy.
