Masterpiece Arms MPA Defender 5.7x28mm 20 Round Pistol Magazine Review

First Impressions of Masterpiece Arms MPA Defender 5.7x28mm 20 Round Pistol Magazine

The Masterpiece Arms MPA Defender series has always piqued my interest, largely due to its unique design and chambering in the zippy 5.7x28mm. However, the magazine, often an unsung hero in firearm performance, is where reliability either shines or fails. Today, we’re diving deep into the Masterpiece Arms MPA Defender 5.7x28mm 20 Round Pistol Magazine, and I’m eager to see if it lives up to the expectations set by the firearm it feeds.

I’ve been on the hunt for magazines that provide both high capacity and unwavering reliability, especially in less common calibers like 5.7x28mm. Many magazines on the market, especially for niche firearms, suffer from feeding issues or questionable durability. I was hoping the MPA Defender magazine would offer a solution.

Upon unboxing, the magazine felt solid, with a reassuring weight and a seemingly robust polymer construction. The black finish was consistent, and the overall design appeared functional, though not particularly flashy. Compared to some aftermarket Glock magazines I’ve tested, the MPA magazine seemed to have a more refined finish and a sturdier feel.

I chose this particular magazine because it’s the factory-original magazine for the MPA Defender. This theoretically ensures optimal compatibility and function, compared to third-party alternatives that may or may not work reliably. My first impression was cautiously optimistic. I hoped the range would validate that initial feeling.

Real-World Testing: Putting Masterpiece Arms MPA Defender 5.7x28mm 20 Round Pistol Magazine to the Test

First Use Experience

My initial testing took place at an outdoor shooting range, under relatively favorable conditions – sunny, dry, and temperatures in the mid-70s. I loaded the magazine with 20 rounds of FN 5.7x28mm ammunition and inserted it into my MPA Defender pistol. The magazine seated securely with a positive click.

During my first magazine dump, there were no immediate issues. Rounds fed smoothly, and the magazine ejected cleanly after firing. However, I noted that the follower seemed to have a slight tendency to bind towards the end of the magazine capacity.

Extended Use & Reliability

After several weeks of use, including approximately 500 rounds fired, the MPA Defender magazine has proven to be reasonably reliable. I did experience a handful of failures to feed (approximately 3-4) related to the follower issue mentioned earlier, usually occurring within the last 3-4 rounds of the magazine. The magazine shows minimal signs of wear, mainly slight scuffing on the polymer body from insertion and removal.

Cleaning and maintenance are straightforward; a quick wipe-down with a cloth and a bore snake through the magazine body keeps it running. Compared to some of the cheaper 5.7x28mm magazines I’ve used in the past, the Masterpiece Arms magazine is significantly more durable and reliable, although not flawless.
