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.
