I took the Range Officer back to the range yesterday to try out the Harrison sight. 250 rounds later and I still like it. It did change my POA/POI relationship a little bit as it now strikes about 1" lower at 15 yards.
No problems of any kind running the Magtech 230gr FMJ through the pistol. I was pleased with the accuracy and put up this group at 15 yards shooting offhand (no rest). Four out of five into about one inch. I jerked the trigger a bit on the flyer.
I know I said it shoots low, but I quit using a six o'clock hold to shoot this group. The original target sight was right on with the six o'clock hold (at the factory setting) but this one works better if I cover the desired POI with the front sight.
I should have a report on the new Dawson Precision tritium front sight in a week or so after I get it installed and shoot with it.
