AMER XLTALL GLK 17-39 GRN/ORG/BLK Review

First Thoughts on the AMER XLTALL GLK 17-39 GRN/ORG/BLK

The AMER XLTALL GLK 17-39 GRN/ORG/BLK suppressor height sights promise a clear sight picture and reliable backup for red dot optics on Glock pistols. Ameriglo is known for its quality sights, and these, with their distinctive green/orange front and blacked-out rear, aim to provide rapid target acquisition. These sights offer an elevated height that makes them ideal for use with suppressors or raised optics platforms.

I was looking for a set of backup sights for my Glock 19 MOS that wouldn’t interfere with my Holosun 507C, but would still be functional should the optic fail. I needed something taller than standard, robust enough for daily carry, and visible in various lighting conditions. I ultimately chose the AMER XLTALL GLK 17-39 GRN/ORG/BLK due to its favorable reviews, reasonable price point, and the appealing green/orange front sight.

Upon unboxing, the sights looked well-machined and the color combination was striking; a vibrant green front sight with an orange outline, contrasted against a matte black rear. The steel felt solid and the finish appeared durable, inspiring confidence in their ability to withstand regular use. They seemed taller than the stock Glock sights, as expected, but not excessively so. I had considered Trijicon Bright & Tough suppressor sights and the Night Fision Optics Ready Stealth Series, but the AMER XLTALL GLK 17-39 GRN/ORG/BLK seemed like a better value proposition.

My initial reaction was positive; these sights appear to be exactly what I needed. They seem like a well-built, practical solution for backup sights that co-witness with a red dot without being distracting. Time will tell how they perform under real-world conditions, but my first impression is one of anticipation.

Real-World Testing: Putting AMER XLTALL GLK 17-39 GRN/ORG/BLK to the Test

First Use Experience

I first tested the AMER XLTALL GLK 17-39 GRN/ORG/BLK sights at an indoor shooting range, focusing on rapid target acquisition and co-witnessing with my red dot. The lighting conditions varied from bright to dimly lit, simulating different environments. I focused on drawing from concealment and quickly acquiring a sight picture.

The high-visibility green front sight immediately stood out, making it easy to pick up even in low light conditions. The blacked-out rear sight proved to be excellent as it eliminated any distractions and allowed me to focus on the front sight and my red dot. I found the height to be perfect; they cleared my suppressor and co-witnessed in the lower third of my optic window. After a few magazines, the sights were intuitive and effective. There were no immediately apparent issues.

Extended Use & Reliability

After several months of use, including weekly range trips and daily carry, the AMER XLTALL GLK 17-39 GRN/ORG/BLK sights have held up remarkably well. I have put roughly 2000 rounds downrange since installing them. The finish shows minimal wear, mainly around the edges of the rear sight.

Cleaning is straightforward, requiring only a brush and solvent to remove powder residue. The sights have maintained their zero and continue to offer a clear and reliable sight picture. Compared to standard Glock sights, these are significantly more visible and easier to acquire, especially in less-than-ideal lighting. These sights have exceeded my expectations.
