Zardos- it’s shoots POA for me. It’ll present you with a heinie straight 8 like sight picture if you are familiar with that. Just put 1 dot on top of the other.
As stated my current preference is for something bolder and nothing on the rear sight, but this certainly works for me- it’s just not as quick for my aging eyes.
CZC was very quick with all the sight purchases I’ve made with them, so work with them with confidence
