For many, including CR920 users, the Holosun 507K stands out as the preferred subcompact red dot sight. Its sleek profile aligns seamlessly with the slide width, making it ideal for concealed carry.

Improved Durability - The Holosun 507K is comparable to the Trijicon RMR in terms of resisting drop impacts and handling the recoil of small 9mm firearms. Suitable for CR920s with or without a slide window cut.

Activates via motion sensor - The ShakeAwake technology saves more battery juice when the optic is sitting in idle.

Simple battery change without hassle - No sight removal is required for a battery swap.

Fast Reticle Acquisition - Highly recommend using a suppressor height Glock 43 front sight co-witness to pick up the dot faster

The new Holosun EPS is a fully enclosed IPX 8 micro red dot sight like the Holosun 509T, but the EPS version uses RMSc footprint. It's basically a micro version of the 509T for conceal carry use. It gives the Shadow System CR920 even more of the shoot like a full size pistol experience.

Uses RMSC Footprint - It fits on Shadow System CR920's RMSc slots, and it fits any Glock 43X MOS holsters.

Very Long Battery - 50,000 + hours of CR1620 battery life plus solar panel backup power is more than enough. 

Solar Power BackUp - Functions like a fiber optic under any light exposure

Side Loading Battery - No sight removal required to swap battery. Very user friendly

Swampfox Sentinel - Best For The Money

The Swampfox Sentinel is the best for the money optic for Shadow System CR920. It directly mounts to the RMSc slots, and it features a 7075 T6 aluminum body to keep the optic rugged against recoil forces and occasional bumps and bruises.

Extra Protection - The optional IRONSLIDES Shield can be purchased separately add lens hood protection against direct stress impact on the main lens frame

Low Profile Lens Hood - Aim with both eyes open and see targets clearly 

Manual Model -  Shake ‘N Wake motion sensing preserves battery life when Sentinel-M has been still for about 4 minutes. With new motion, Sentinel-M resumes its previous brightness level. 

Auto Model - A photosensitive sensor adjusts the dot brightness relative to ambient lighting conditions.

TAP Reticle Activation - (Include MOTAC) Just tap the lens hood to dial brightness. Big finger people will love this (8 daytime illumination levels)
