This guide compares the Aimpoint COA, ACRO P2, and Holosun EPS/EPS Carry pistol optics, focusing on their mounting systems and design features. The Aimpoint COA utilizes a proprietary 'A-cut' system for a low profile, while the ACRO P2 offers a different mounting solution. The Holosun EPS is presented as a viable alternative with diverse reticle options. The video emphasizes the importance of understanding these differences for optimal pistol sight selection and potential custom slide modifications.

Quick Summary

The Aimpoint COA is considered a top-tier pistol optic due to its low-profile 'A-cut' mounting system and clean design, but it's currently unavailable to civilians. Alternatives like the Holosun EPS offer greater versatility with multiple reticle options and optional solar power, while the Aimpoint ACRO P2 is another enclosed emitter option. Custom slide milling may be required for optimal direct mounting.

Frequently Asked Questions

What makes the Aimpoint COA a desirable pistol optic?

The Aimpoint COA is highly regarded for its smaller bezels, larger window, and the 'A-cut' mounting system that allows it to sit flush with double-stack 9mm slides, offering a clean sight picture. However, it's currently unavailable to civilians due to government contracts.

What are the main differences between the Aimpoint COA and ACRO P2?

The COA features a lower profile and cleaner aesthetic due to its 'A-cut' mounting system, while the ACRO P2 has a different mounting solution and is generally considered bulkier. Both are enclosed emitter pistol red dots.

What is a good alternative if the Aimpoint COA is unavailable?

The Holosun EPS and EPS Carry are recommended alternatives, offering features like optional solar panels, red or green dots, and various reticle options (2 MOA, 6 MOA, multi-reticle) at a lower price point.

Can I directly mount a Holosun EPS optic to my Glock slide?

Direct mounting often requires specific slide milling. Shark Coast Tactical, for example, offers CNC milling services to achieve a perfect direct-mount fit for optics like the Holosun EPS onto Glock slides.
