To address numerous inquiries about sight compatibility with the Glock 44 .22 Rimfire, here are the recommended options:
- GS805 Target Set, Plain Rear/Fiber Optic .225” tall front AND a .015” G-Shim for a .240” face height. GS805 and G-Shim are sold separately. This combo is ideal because the G-Shim increases the front sight contact surface with the slide. This improves hold on the polymer slide.
- GS922 Target set, Plain Rear/Fiber Optic .245” tall front. This set can work just as well. I just prefer the concept of option 1 on a polymer slide.
- GS412 Defense set, Tritium rear/Tritium .225” tall front with .015” G-Shim for a .240” face height. Defense sets include a G-Shim.
G44 tests were conducted with an experienced GSSF Master Class competitor’s G44 with a GS805 Target set and G-Shim. At 15 yards the point of aim and point of impact was at zero.
Sights must be installed by a qualified gunsmith. This is especially important with the G44 due to the polymer dovetail. Improperly installed rear sights will result in a loose fit, and/or may shear polymer and/or will push the sight off axis. Another problem can happen from over-torquing the set screw. A lot of things can go wrong if you don’t have the knowledge, experience and skills to properly install your sights on ANY pistol. Instead of risking it, find an experienced source to perform the installation.
