Glock 43X NEW OPTIC CUT Tested — Holosun 507K X2 + ACSS Vulcan Reticle EDC Setup range test!

In this video, I test the Glock 43X with the new factory optic cut paired with the Holosun 507K X2 running the ACSS Vulcan reticle from Primary Arms.
We break down how it mounts, how it performs, and how the ACSS Vulcan reticle helps you track your dot faster under stress — from draw to first shot.

This setup is quickly becoming one of the best concealed carry optic combos for slimline Glocks.

Gear Used

Pistol: Glock 43X (New Optic Cut Model)
Optic: Holosun 507K X2 (ACSS Vulcan Reticle)
Mounting Pattern: K Footprint (Slimline MOS Compatible, no Plate needed)
Ammo: 115gr Blazer Brass and 115gr Sellier & Bellot FMJ
Holster: Muddy River Tactical

Why the ACSS Vulcan Works

The ACSS Vulcan reticle uses a center dot with an outer reference ring — when your dot drifts off target, that ring instantly guides your eye back to center. It’s fast, intuitive, and perfect for shooters transitioning from irons to red dots.

Performance Highlights

✅ Fastest sight reacquisition I’ve seen on a micro optic
✅ Ultra-compact & lightweight for CCW
✅ Shake Awake + 50K hr battery life
✅ No plate needed for K-cut optic
⚠️ Smaller window than 507C — trade-off for concealment

Final Thoughts

If you carry a 43X or 48 and want a true EDC-sized optic, the Holosun 507K X2 with the ACSS Vulcan reticle should be on your short list.
It mounts low, runs forever, and the reticle helps keep you on target when it matters most.
