Installing a Trijicon SRO on a Glock MOS Pistol

In deciding to mount a miniature red-dot sight (MRDS) on a handgun, few options are as easy as a Glock Modular Optics System (MOS) pistol. However, if you do your research, you will notice that many experienced users say that having a pistol milled for your particular optic is a more secure, durable option. The reason a custom-milled slide is more secure is that the optic will be cradled in a cutout that is deeper, and only as big as it needs to be. In contrast, when a Trijicon RMR or SRO is mounted on a Glock MOS pistol, there is a small gap in front of, and behind, the optic. Additionally, the optic is secured to the stock plate with only three threads of each mounting screw.

Enter the C&H Precision Adapter Plate; This plate solves the possible problem of not supporting the optic in front and back by the addition of a raised lip in front of the optic. Additionally, the optic sits lower and is supported in the back because the adapter plate is a little thinner than the stock version. Finally, the optic has more threads for the mounting screws, allowing eight threads to take hold.

The mounting instructions were interesting because they advised using some oil to lube the mounting screws. This allows the screws to reach deeper and work better. Rather than Loc-Tite, the user is advised to use clear nail polish to secure the screw-head.

Time will tell how this mounting plate endures. However, for the $60 cost, this plate looks like a good way to increase the chances of success for securing a red dot sight on your handgun.

      The mount is as solid as a rock, and so is the method of using clear nail polish on the heads of the screws instead of using loc-tite.
