Real-World Testing: Putting FAB Defense MPS-12 Magazine Extension to the Test

First Use Experience

I tested the FAB Defense MPS-12 Magazine Extension at my local shooting range. This allowed me to evaluate its performance in a controlled environment. I ran several magazines through my M&P 9 Shield, focusing on feeding reliability and grip comfort.

The weather was dry and mild, perfect for a range day. I experienced no issues with feeding, even with a fully loaded magazine of 12 rounds. The extended grip made a noticeable difference, giving me a more secure and comfortable hold on the pistol.

Installation was straightforward, thanks to the included instructions and Allen wrench. The only minor issue was initially getting the magazine spring seated correctly, but after a few tries, it clicked into place. I was impressed with the improved grip and the added rounds.

Extended Use & Reliability

After several months of regular use, the FAB Defense MPS-12 Magazine Extension has held up remarkably well. I’ve used it in various shooting scenarios, from casual range sessions to more tactical training drills. The extension has consistently performed without any malfunctions.

There are no significant signs of wear and tear on the polymer body. It has withstood repeated magazine changes and regular cleaning without any cracking or deformation. I clean the extension every time I clean my pistol, which involves a quick wipe-down with a CLP (Cleaner, Lubricant, Protectant).

Compared to my previous experience with a similar magazine extension from a different brand, the FAB Defense MPS-12 Magazine Extension is far superior. The FAB Defense product maintains its shape and integrity, whereas the other brand began to show wear and tear after only a few months. It has certainly exceeded my expectations.
