Eugenio, member, from Buenos Aires, Argentina, asked on October 07, 2024

Is it suitable for a Glock 40 MOS 10mm Auto? Thanks

Expert Answer
A
Answered by Ethan, Gear Expert, from IL, United States, on October 07, 2024

To mount the Holosun HS507K Compact Pistol Red Dot Sight to your Glock 40 MOS, you will need to use the C&H Precision Weapons V4 MIL/LEO Adapter Plate (linked below). Keep in mind that this optic was designed for micro pistols, while your Glock 40 can accept optics with full sized footprints such as the RMR, Deltapoint Pro, Docter, and C-More footprints.
