The Sig Romeo Zero Elite is for any Sig P322 owners that want an Sig Sauer branded RMSc footprint red dot sight and without spending over $300 for an optic.

Suited For 22LR Use - For the money, this optic is rated for 22LR use

Much More Impact Resistant - The shroud protects polymer frame ROMEO Zero underneath

New Glass Lens - Aspherical glass lens eliminates glass edge distortion (Not polymer lens)

Touch Activation - The new TAP (Touch Activated Programming) allows people with big hands to adjust the brightness without messing around with small buttons

Super Lightweght - Even with the metal shroud, the optic still weighs like nothing

Multi-Reticle Options - Choose between a single dot or a 32 MOA ring dot

The Holosun HS507K X2 micro red dot sight is very popular for all RMSc footprint pistols. This one is a top option for the Sig P322.

Fast Target Red Dot Acquisition - Shoot 22 LR at bowling pins, cans and steel plates with ease

Activates via motion sensor - The Holosun ShakeAwake technology instantly activates the red dot reticle upon sensing motion & deactivates when not in motion to save more battery juice (CR1632 battery)

Recoil Proven Glass Lens - This optic works on a 357 Sig, so shooting 22 LR is not a problem at all

Simple battery change without hassle - Access battery from the side tray instead of the bottom. No sight removal or re-zeroing required

The Swampfox Sentinel is a top selling RMSc red dot sight, and it's a great 7075 T6 aluminum body optic for the Sig P322. It mounts DIRECTLY to P322 slide without any mod

Durable Slim Body - The forged body is just like the 507K X2 for reliable duty carry but with a much slimmer lens hood profile

Extra Protection - The IRONSLIDES SHIELD can add additional lens hood protection against barricade racking, drop, and other physical impacts to protect the internals.

Low Profile Lens Hood - Aim with both eyes open without thick lens frame getting in the way 

Manual Model -  Sentinel-M resumes its previous brightness level. Highly recommend manual version for indoor low light use. 

Auto Model - A photosensitive ambient light sensor provides dot brightness relative to ambient lighting conditions.
