Trijicon MRO - Largest Field Of View
The Trijicon Miniature Rifle Optic has the largest circular field of view among other tube style red dot optics for max situational awareness. It's fully enclosed unlike the Holosun 510C that I have recommended. This optic is designed for duty use in the field.
Increased Situational Awareness - Tapered tube design widens the field of view while eliminating the tube effect for improved situational awareness.
Large Field Of View - The tapered body design allows the tube to remain small while giving the shooter a wide view.
Battle Proven Durability - The 7075 T6 aluminum body is as tough as a little tank. Handle rough handling, drops, recoils and kicks like its nothing!
For the price, the MRO is a better option for anyone just got started with shooting. If you're new and want something as tough as the Aimpoint but without spending over $800 please check the best price by clicking on the button below.
Pros
- No tube effect - wide FOV
- Much more affordable than Aimpoint Micro
- Minimal side profile FOV obstruction
- Accepts various aftermarket optic mounts
- Mil Spec durability
Cons
- Lens tint could be reduced more for better clarity

The Trijicon SRO is a great choice instead of the old Trijicon RMR for the range Ruger PC Carbine. It's window makes plinking so much more fun than hunting for that reticle. But there are more:
Easy Battery Change - You can change the battery from the side without taking off the sight. This way is better than the Trijicon RMR.
Bigger Buttons - The new model has bigger buttons that are easier to press.
Long Battery Life - With Shake Awake and a solar panel, the battery lasts over 50,000 hours. If the sight moves, it turns on to save power. If the battery dies, the solar panel keeps it working.
Pros
- Wider FOV than RMR
- Minimal side profile FOV obstruction
- Top battery loading design
- Accepts various aftermarket optic mounts
Cons
- Open emitter
- No audible turret dial
Sig ROMEO 5 - Best Value
Why Try The Sig Romeo 5 - The Sig ROMEO5 1X20mm is an robust, compact and affordable red dot optic. It's by far the hottest selling optic for Ruger pistol carbine and other centerfire rifles. We highly recommended red dot sight for new gun owners before moving to top tier products
2 MOA dot size with 10 illumination settings including 2-night vision works extremely well in all light conditions.
No Lens Tint - Very little lens tint for a clear sight picture under the sunlight and low light
Accepts various mounts - Use any Aimpoint Micro mounts available on the market (Recommend low mount for the Ruger PC9)
Pros
- Slick outer body profile
- Positive click feedback MOA turrets
- Affordable for beginner
- Uses Aimpoint Micro mounts
Cons
- Max brightness setting not bright enough under direct sunlight
Vortex VENOM - Lightest Weight
No products found.
I recently had the chance to use the Vortex VENOM red dot to build the lightest Ruger PC9 setup, and I must say, it's quite good. Just like the Burris FastFire 3, it's super low profile and lightweight, which is what I wanted without spending a lot of money.
I've seen it become a favorite among many shooters, not just for pistols but also for PCCs. One thing that really stood out to me was its slim design.
The way it streamlined the gun's profile without adding bulk was impressive. Overall, the 3 MOA or the 6 MOA Vortex VENOM is a solid choice for anyone looking to enhance their shooting experience, offering a great balance of size, weight, and versatility.
Pros
- Very low profile design
- Positive click feedback MOA turrets
- Pictainny screw mount included
- Very clean edge to edge glass clarity
Cons
- Doesn't retain zero after hard drop - could shatter the glass

Ruger PC9 Co-Witness Mount
The Ruger 9mm PC comes with Picatinny rail on top of the receiver. Any mount would work whether to be QD or thumb screw mounts.
The tip of the front sight post is about 7/8" above the bore, and the top rail is closer to the bore than for a standard flat-top AR15.
We recommend the Midwest Industries Side red dot mount (For Aimpoint Micro footprint ONLY) exclusive with the MI-CRPC9X MLOK rail for the best 1/3 co-witness on the Ruger PC9.
Reticle Size
9mm PCC is great for close quarter, therefore a 2 to 6 MOA size reticle are perfect for engaging targets up to 100 yards with a tight group.
Since 9mm isn't a precision round, so having a large MOA dot over the target gives the shooter the coverage area for effective hits.
