XS F8 Night Sight Set Sig P320 P225 P226 P229 Springfield XD FN 509

The XS F8 Night Sight Set is a pair of iron sights for handguns, built around tritium front and rear sights that glow in low light to aid alignment. The front sight carries a high-visibility orange ring, and the rear sight has a wide notch that draws the eye to the top edges of the sight for consistent alignment.

The set uses a round-base notch, a rear sight overhang intended to reduce glare in bright daylight, and a rear sight ledge that assists one-handed slide manipulation. Installation is by hand or with a sight pusher tool. The sights are offered in green.

The set is listed as fitting Sig P225, P226, P229 and P320 pistols, Springfield XD, XDm and XDs pistols, and the FN 509.
