Let’s Talk About Glock 7.3MM Fixed Rear Polymer Sight
The Glock 7.3MM Fixed Rear Polymer Sight is a seemingly simple component, yet it plays a critical role in the accuracy and usability of any Glock pistol. This factory-standard sight, manufactured by Glock, is designed as a direct replacement or upgrade for existing sights. It offers a fixed point of reference for aiming. Its polymer construction keeps the overall weight down while providing adequate durability for typical use.
I was initially drawn to this sight after noticing some significant accuracy issues with a used Glock 19 I had acquired. The original rear sight was worn and slightly loose, affecting my groupings at the range. I needed a cost-effective and reliable solution to restore the pistol’s original accuracy and consistency.
Upon receiving the Glock 7.3MM Fixed Rear Polymer Sight, I was immediately struck by its straightforward design. The polymer material felt surprisingly robust for its size, and the matte black finish was consistent with the factory look of my Glock. Its lightweight nature was also appreciated, as I didn’t want to add unnecessary weight to the slide.
Compared to aftermarket steel sights that I considered, the Glock polymer sight stood out due to its affordability and ease of installation. While steel sights offer superior durability, they often come with a higher price tag and may require professional installation. The Glock sight promised a simple, drop-in replacement without the added cost or complexity. I wanted to keep things simple and original.
My first impression was a pleasant surprise. I expected a cheap, flimsy piece of plastic, but the Glock 7.3MM Fixed Rear Polymer Sight felt like a quality component designed to meet the demands of everyday carry and range use. It offered a budget-friendly way to improve my pistol’s accuracy.

The ease of use was immediately apparent, and I didn’t need any adjustment period. My groupings tightened considerably compared to the old worn sights, indicating a clear improvement in accuracy. There were no unexpected issues or surprises during the initial range session.
