We have tested a handful of sights based on their durability, reticle, battery life and cost.
Here are the best red dot sights for STI Staccato series handguns. We will also include links for aftermarket adapter plates at the end.
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 perfect match for a high premium handgun like the STI Staccato. It's the 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 big POV sight for fast action shooting!
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
Leupold DeltaPoint Pro (2.5 MOA / Delta Reticle) - Best For Old School
Larger Window Than RMR - If comparing RMR and the DPP, the DPP 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
