My advice, call S&W tomorrow. They will give you an #RMA number and send you a freebie return label. Ship it off on their dime and get it checked. I am shipping mine tomorrow. It blew up. (Don't ask)
First time shooting these sights. Other than the obvious, are there any tips on using them?
Painting the front sight orange really tightened the groups size.
Putting 25% of the front sight above the notch centers the group.
