Things I liked:Easy to mount and use. Big improvement over original piece of metal they call a sight that came with the gun. Things I would have changed:nothing What others should know:Take your time mounting and make sure it is square on the breech. Used a laser boresighter for initial adjustment and then fine adjustments during shooting were easy.
Things I liked:Not much. Things I would have changed:Red dot too bright for me. What others should know:mounted it on a 1322 pistol.Did not like the way it sat on the breech. Red dot too bright. Easy to knock out of adjustment.
