The SIG SAUER factory walkthrough breaks it down into six steps: clear the firearm, field-strip the slide, remove the optic plate, prep and seat the optic with the dovetail wedge, torque the screws to 18 inch-pounds, and reassemble for a function check. This guide follows the manufacturer's own installation video on Greyhive, where the SIG SAUER technician walks through every step on a SIG-LOC compatible pistol. It's the cleanest reference for owners mounting a SIG-LOC COMPACT for the first time — no guesswork on torque, screw sequence, or what to do with the factory cover plate. Key Takeaways Always clear the chamber and remove the magazine before disassembly — confirmed first step in the SIG SAUER tutorial. Field-strip the pistol completely: rotate the takedown lever, drop the slide catch, then remove the slide, recoil assembly, and barrel.
