The Force Esse has its own pair of red dot mounts, made by Toni System for this model rather than taken from the general Tanfoglio range. If you want an optic on a Force Esse, these are the parts to choose.
What they do
Each one replaces the factory rear in its slot. The slide is not milled, and you can return to iron sights by refitting the original rear.
Two footprints
The A mount suits the smaller RMSc, DPP and Docter bases often found on compact optics. Type B takes the Trijicon RMR or C-More RTS pattern, used on many full size pistol optics. Look at the base of your optic, or its specification, and pick the letter that matches.
After fitting
Zero the dot at your usual distance and recheck the screws after the first session. While it is fitted, you aim with the dot alone.
Both mounts are in Red dot mounts for Tanfoglio Force Esse.
