The TRYBE Optics Micro Red Dot is cut for the RMSc optic footprint. The variance among different pistols or even the same models can vary widely. OEM documentation is the best source to ensure a proper match. That said, if the firearm does not have the RMSc footprint, then the optic may still fit, but it would require an adapter plate that converts the footprint found on the firearm to the RMSc.
