Built for Red Dots & Suppressors – XL Tall, Optic Compatible Design
The AmeriGlo GL452 is purpose-built to work with slide-mounted pistol red dots and suppressed Glock pistols:

Suppressor-height clearance – The extra-tall sight profile clears most common pistol suppressers, giving you a full sight picture over the can instead of guessing your point of aim. GlockStore+2Mounts Plus+2
