5 Best Red Dot Sights for FN 509 Series Pistols
Trijicon SRO - Largest FOV
Why we picked this one - The SRO is by far the best large window optic for the FN 509, FN 509 LS Edge, and other handguns for fast target acquisition. The design, looks and color matching are just pure sex on the FN 509.
Bigger Window - Acquire the dot fast and consistent even if you're slightly off center. Spend no time looking for the reticle or get lost in the window during follow up shots.
Easier Battery Access - Load/Replace battery right from the top! No sight removal or re-zero required
Better Follow Up - Reacquire sight after follow-up shots muzzle flip without losing the dot inside the window.
Same RMR mounting footprint - Using the exact Trijicon RMR mounting footprint keeps everything compatible without having to buy special accessories.
Holosun 507C X2 - Best Overall
Why people love Holosun 507C X2 - The Holosun HE507C X2 does the same thing the original model does but better in every way that improved the shooting experience while still remains affordable.
NEW ACSS Model - Watch the 250 MOA outer ring guides the eye back to the reticle center
Uses RMR Footprint - No special adapter or milling required! Just use the same Trijicon RMR adaptor plate that comes with the FN 509 Tactical.
Bigger Buttons - Adjustment buttons in the dark or day easily even with big fingers
Near Infinite Battery life - 50,000 hours of battery life plus solar panel backup power if the battery goes out.
Side Loading Battery - This eliminates the need to remove the sight for battery swap and re-zeroing. Access the battery from the side tray
Solar Power BackUp - Solar fail-safe power kicks in immediately when the battery dies, so the optic will always remain on and ready.
At this price point, which is the lowest it's ever been for a Trijicon RMR alike sight, You'll save a ton of money. Just make sure to click the button below for the best deal.
Trijicon RMR = Best Durability
Trijicon RMR RM07-C-700679
is the grand father of all modern red dot sights. This is the most durable for duty use on your FN 509 pistol.
Multi MOA Dot Size Options - Highly recommend 6.5 MOA model for FN 509
Improved G Performance - The RMR Type 2 grips the battery tighter to prevent loose electrical contact
Slide Racking Assist - RMR is very rugged for slide racking against any hard surfaces.
Leupold DeltaPoint Pro - Large FOV Like SRO
The DeltaPoint Pro is Leupold's best open emitter red dot sight. The field of view is as much as a Trijicon SRO but in a rectangular shape. The FN 509 comes with adapter plate and spacer to fit the DeltaPoint pro right out of the box.
Larger Window Than RMR - The field of view is so much bigger than Trijicon RMR, and the optic height is just right for most shooters
6 MOA and 2.5 MOA - 6 MOA option is much easier to see and it's now available for shooters with astigmatism
Extra Lens Hood Protection - The added lens hood protects the optic from receiving direct impact that increases durability and making it fail proof.
Easier Battery Access - Load/Replace battery right from the top! No sight removal or re-zero required. This user friendly design has been implemented into many other new optics today.
Vortex Venom - Best Value
Why we pick this one - The Vortex Venom is a entry level (3 or 6 MOA sold separately) rapid target acquisition sight just like the Leupold DeltaPoint Pro. Without spending over $300, this is a rock solid optic for range use and competition.
Top-Loading Battery Access - Install battery right from the top without removing the whole sight or having to re-zero the sight afterwards
Multiple Intensity Settings - Rapid target engagement under a full range of lighting conditions
Wide Field of View - Thin lens hood frame doesn't obscure the shooter's field of view for better sight acquisition and not lose the dot.
Super Lightweight - Weighing only 1.1 oz built with rugged aluminum housing, helps for high speed shooting
