As a long-time fan of the 5.7x28mm cartridge, I jumped at the chance to get my hands on the new FN Five-SeveN MK3 magazine for my trusty pistol. With its impressive 20-round capacity and reliable performance, I was eager to put it through its paces and see if it lives up to the hype. In this review, I’ll dive into my experience with the magazine, highlighting its strengths and weaknesses, and giving you the lowdown on whether it’s worth the investment for your own 5.7x28mm rig.
Design and Build Quality
The first thing that caught my eye was the FN Five-SeveN MK3 magazine’s sleek and compact design. At only 6.1 inches long and 1.2 inches wide, it’s easy to conceal and discreetly stash in a belt or waistband. The magazine itself is made from durable polymer, with a matte finish that shows off the gun’s ruggedized aesthetic. The design is straightforward and functional, with a comfortable contoured grip that nestles well in the hand.
Capacity and Reliability
Now, about that impressive 20-round capacity: the FN Five-SeveN MK3 delivers. Made from a single piece of folded steel, the spring is robust and reliable, cycling smoothly through the double-stack design. I encountered zero issues with feeding or extraction, even with a mix of 40-grain and 50-grain ammunition. Translated to real-world usage: if you’re someone who likes to go full-tilt into the fray or needs a little extra insurance, the FN Five-SeveN MK3 will keep you in the fight.
