The gun is a 4 5/8" Flattop, from the Ruger run, not Lipsey's. The trigger is typical Ruger: a bit draggy and heavy.
I don't really call shots less than two inches out "flyers" but if you choose to, feel free to blame me! I don't recall where in the multi-hour shooting session I fired that group, but if it was towards the end, eye fatigue does come into play. Also just plain fatigue, to be honest.
I shoot handgun groups with wrists on a sandbag but the gun unsupported.
