If I remember correctly 1 click is 1MOA. There is a math formula for it but don't remember. Maybe one of the pistol folks will be along and have a for sure answer.
All that I want to know is how far does the rear sight move left or right with one turn of the knob. Beyond that, I can calculate anything.
I checked the Buck Mark owner’s manual, available on Browning’s website. Unsurprisingly, it just says to move the rear sight left or right to move the point of impact. That’s typical for a pistol. .22 ammunition is cheap, it should be inexpensive and easy to sight in your Browning.
