Will this fit onto my Glock 19x mos? Expert Answer

Will if mount on a Glock 43x mos Expert Answer

No, the Glock 43X is designed to accept optics that utilize the smaller RMSc footprint. The correct model would be the CCW version, which can be found linked below:

Good stuff by One eyed jack, Verified Owner, November 15, 2025
I have dots, the only one I didn't get from optics planet was a fake. Don't get fooled and get the real stuff at a fair price.

Easy Install, spot on performance. by juankt, Verified Owner, November 8, 2025
Was very impressed that it came with an array of mounting hardware. Likely covers a majority of platforms. Took less than 5 minjtes to install, and a mere 8 rounds to zero the dot. Love the fov and the visibility of the dot.
