How this slide mounts an opticThe RXM uses its own cut with adapter plates rather than the GLOCK MOS pocket, despite the gun's broad GLOCK parts compatibility. Plate coverage is now good across RMR, K/RMSc, DPP and ACRO. The factory iron sights sit high enough that tall optics foul them: Steiner MPS and K-series and low-deck DeltaPoint variants clear, while RMRs and SROs generally do not, and 507C and ACRO fits are marginal. Shops offer a 'MOS+' re-mill that converts it to MOS-compatible plates, at the cost of the factory irons.
The interactive
fit checker opens with this pistol already selected and gives
you a single verdict for any optic, plus a build sheet with the plate SKU, screw threads, torque figures
and install order. Every "how it mounts" cell above opens that pairing's verdict — the most asked-about ones on a page of their own, the rest in the
fit checker — at an address you can send to someone.

this is worth more than a spec sheet — and nothing here changes without a source, so bring one.
