Glock 43X MOS

The Glock 43X MOS adds the two features most requested on the original 43X: an optic-ready slide and an accessory rail. The MOS slide accepts Shield RMSc footprint optics directly (no adapter plates), making it compatible with popular micro dots like the Holosun 407K/507K and Shield RMSc. The integrated slim rail accepts compact lights like the Streamlight TLR-7 sub.

This transforms the 43X from a "just the gun" carry pistol into a fully-featured defensive package. Combined with Shield Arms S15 magazines, the 43X MOS provides 15+1 capacity, optic capability, and weapon light compatibility in a package that still conceals easily. This is the configuration many consider the ultimate concealed carry Glock.

The MOS slide uses a Shield RMSc footprint directly machined into the slide rather than adapter plates, providing a lower optic mount than full-size MOS pistols. The front accessory rail is narrower than G17/G19 rails but accepts lights designed for slim pistols.
