Remove your rear sight by loosening the set screw in the top, and drifting it from left to right.
Install the rear sight onto the mount by pressing it into the dovetail from right to left. There is an arrow engraved in the mount to indicate the correct direction. Center the sight in the dovetail. Lock the sight in place by tightening the set screw in the top of the sight.
Install the new front sight using the original screw. Do not exceed 5 in-lbs!

Perform a function check and make sure the pistol is safe to fire.
