We have tested a handful of sights based on their durability, reticle, battery life and cost.

Let's check them out:

Best Reflex Sights For STI Staccato

Trijicon RMR Type 2 RM07 (6.5 MOA) - Best Overall

Referenced 1911 Forum

Why this is the go-to optic - Trijicon RMR is the gold standard for micro pistol reflex sights . It's the one optic that sets the bar for all competitive optics on the market today.

Improved Accuracy - Big and easy to acquire 6.5 MOA dot works for shooters with astigmatism without having to crank up the brightness

Built For Handgun - The RMR Type 2 is specifically built to handle handgun slide G force. The new battery compartment grips the battery tighter to prevent loose contact

Slide Racking Assist - Racking the slide one handed against hard surfaces to clear jams or get into battery. Tough rugged housing doesn't throw off zero

Trijicon SRO (5 MOA) - Largest FOV

Referenced 1911 Forum

Why we picked this one - Acquire the red dot in the center of the lens much easier than any other optics. This means less time spend looking for the reticle or get lost in the window during follow up shots.

While mounted on a STI Staccato, it's just a perfect match!

Bigger Window  - Englarged window size compensates for slightly off center pistol draw presentation, so the shooter still able to acquire the dot and get it back to the center.

Easier Battery Access - Load/Replace battery right from the top! No sight removal or re-zero required

Better Follow Up - Better follow-up shots without losing the dot inside the window combined with STI Staccto's butter smooth slide cycling action to help the shooter get back on target as soon as the trigger reset

Same RMR mounting footprint - Swap out your Holosun 507C or RMR off your Staccato without buying additional plates or custom fit

Referenced STI

Why Use The DeltaPoint Pro reflex sight - Leupold DDP is a classic large window red dot sight back in the day. It's older than most of the newer products on the market, but it still serves shooters very well.


Larger Window Than RMR - If comparing RMR and the DDP, DDP wins the large window size for better sight acquisition on STI Staccato XC

Extra Housing 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! It's the user friendly design that many other optics are starting to implement
