I have never shot so well, as with this red dot. This was a new optic on a new Walther PDP F. After warning up with about 8 rounds, the remaining 32 rounds were either in the bullseye, or 1st ring outside it. I am normally just an average shooter, certainly not a good shooter, and am a 70+ yo lady with vision issues. These results were directly attributable to the optic, I do believe.
