do “glock switches” for a G19 work in a Ruger RXM?

No, Glock switches, which are devices designed to modify Glock handguns to fire automatically, are not compatible with Ruger firearms, including the Ruger RXM. Glock switches are specifically engineered for the internal mechanics of Glock pistols. The Ruger RXM operates on a different design and mechanism. Additionally, altering firearms in this way can be illegal and poses significant safety risks. It's crucial to adhere to firearm laws and regulations in your jurisdiction.
