Ruger RXM parts compatibility

Short answer: Ruger says most major RXM components are designed for Glock Gen 3 compatibility, and the pistol uses 9mm magazines that fit compact or larger double-stack Glock pistols, including Magpul GL9. Do not assume every Gen 3 slide, barrel, or frame part fits. This store lists 10-round magazines. It does not sell the pistol.
Ruger describes a removable stainless steel fire control insert inside a Magpul EHG grip, and a slide that direct-mounts RMR, DPP, and RMSc. This store does not sell that insert. The Magpul grip in stock is titled RXM compact. The True Precision slide title says RMR cut. Do not read more optic detail into that listing than the title prints.
Barrels and springs: The Ruger threaded barrel kit says it fits the Ruger RXM and is threaded 1/2x28. True Precision sells an RXM barrel and an RXM recoil kit as their own titles. The Radian Ramjet listing for the RXM is a 4.0 barrel: Ramjet fit guide. A Timney Alpha for the RXM is a separate trigger and is not stocked on this page.
Holster and magwell: The MFT holster is titled Ruger RXM. The Icarus magwell title lists RXM, Zev, and OZ9. Match the title. Ruger named holsters in that Gen 3 compatibility line. A Glock 19 holster is still not an RXM holster unless the title says so.
