may well be wonderful as a 'put it on the spot and press' thing, but- for me at least- it can make shooting for accuracy a bit difficult compared to straight crosshairs. Shouldn't, but seems to. Something about keeping the dot centered on the bullseye.
It was a good day at the range anyway, about which I have something else to write, except I just realized 'no pictures'. So that part'll have to come later. But it worked.
Did get a chance to shoot something interesting: a Ruger Blackhawk in
Mind you, if you were close to a bad guy the muzzle blast might well cause enough disruption to send them away(possibly with a shirt on fire).
