Frequently Asked Questions

Will this fit my M&P?

This set fits the S&W M&P (including Shield, but excluding .22 Compact/C.O.R.E. models) and the SD9/SD40 (excluding VE models); confirm your exact variant before ordering.

Why is the rear fiber yellow instead of green?

Yellow fiber-optics are intentionally dimmer than green so the front sight stands out against the rear.
