Introducing an innovative solution for mounting optics to your pistol slide: The Versa Tactical SIGHTSECURE dovetail mount. Available for Beretta and for Glock. To purchase, head to this link: https://partsonly.ca/product/glock-dovetail-optic-mounting-kit/ This system allows the user to install an optic on a slide that does not have an optic cut. Made of a solid piece of 4340 steel, this mount will not bend or break. Has been extensively field tested with thousands of rounds fired. There are no moving parts, latches or other components to wear/break. Simply slide the Versa Tactical mount in the slot where your factory rear sight goes, and install the 2 expander screws. Then your optic is ready to go on! This mount allows for mounting of any industry standard RMR footprint optic. We recommend using a small amount of blue loctite for installation of all the hardware. Ensure the expander screws are inserted until flush and snug, but do not over-tighten! We recommend tightening of the optic mounting screws to either 14in-lbs or to your optic manufacturer's specification, whichever is lower.
