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

Referenced 1911 Forum

The Trijicon RMR sets the standard for all competitive optics on the market today, making it the ideal red dot sight for premium handguns like the STI Staccato.

Improved Accuracy - 6.5 MOA dot works best for shooters with astigmatism. It provides crisp and a rounder dot to see.

Built For Handgun - The RMR Type 2 is designed specifically to withstand the G forces of a handgun slide, and its new battery compartment securely holds the battery to prevent any loose contact.

Slide Racking Assist - Racking the slide with one hand against hard surfaces to clear jams or chamber a round doesn't affect the zero due to its tough and rugged housing.

Trijicon SRO (5 MOA) - Largest Circular FOV

The Trijicon SRO allows for quicker acquisition of the red dot in the center of the lens compared to other optics.

This means less time spent searching for the reticle or getting disoriented in the window during follow-up shots. When mounted on a STI Staccato, it provides an excellent wide field of view 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 - Not lose the dot within the window. In addition, STI Staccto's butter smooth slide cycling action helps the shooter get back on target as soon as the trigger reset

Same RMR mounting footprint - Mount the optic on existing STI Staccto compatible RMR optic plates

Leupold DeltaPoint Pro - Best Rectangular FOV

The Leupold DeltaPoint Pro is a traditional, large window red dot sight from the past. While it's older than many newer products on the market, it continues to serve shooters effectively.

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

People adore the Holosun 507K X2 for several reasons. It's the smaller version of the Holosun 507K X2, designed to fit seamlessly on STI 2011 style pistols like the STI Staccato DUO, thanks to its super slim and compact build.

What's more, it comes at a price point of under $290, allowing you to save a substantial amount of money after you already put in $2500 for a Staccato pistol.

Rugged Construction - Straight cuts, thick 7075 T6 aluminum lens frame and rounded edges to divert impact stress away from the glass for increased durability

Very Long Battery life - The Shake Awake technology saves tons of battery life by deactivating the optic when at rest, then turns it back on upon movement. 

Side Loading Battery - Access CR1632 battery from the side tray instead of the bottom. Just like the top loading ones that eliminate the need to remove the sight for battery swap
