Frequently Asked Questions

What makes the Ruger RXM modular?

The Ruger RXM's modularity stems from its Fire Control Insert (FCI), which is the serialized component. This allows the frame to be a non-firearm accessory, enabling easy swapping between different frames like polymer or aluminum aftermarket options.

Is the Ruger RXM compatible with Glock parts?

Yes, the Ruger RXM is designed to be highly compatible with many Glock Gen 3 19 parts. This includes magazines, slide locks, slide stops, and most internal upper components, effectively making it a Gen 3 Glock 19 clone.

How is the Fire Control Insert (FCI) removed from the Ruger RXM?

The FCI is secured by three pins within the frame. These pins can be driven out using a punch or similar tool, allowing the FCI to be removed from the polymer frame for transfer or reassembly into another compatible frame.

What optics can be mounted directly on the Ruger RXM?

The Ruger RXM features a specialized optic mounting system with posts that allow for direct mounting of popular red dot sights such as the Trijicon RMR and various Holosun C-series models, eliminating the need for adapter plates.
