We’ve had quite a few questions about what accessories are compatible with the CR920, so today we are going to talk about optics, holsters, lights for the CR920. When looking for holsters, you will want a holster designed for a 43X MOS or a 48 MOS. Lights we have tested are the Streamlight TLR-7 sub and the Surefire XSC. In your manual, you will find a table with what optics and screws will fit the pistol. You can find that chart here: Optic Cut – Shadow Systems cut If you have questions about other accessories or fitment, please ask our Technical Team at support@shadowsystemscorp.com
