ProMag S&W M&P Shield 9mm 10 rd Black Finish – 9mm Caliber, 10 Rounds, Steel, Aftermarket Origin Review

The ProMag S&W M&P Shield 9mm 10 rd Black Finish – 9mm Caliber, 10 Rounds, Steel, Aftermarket Origin Made a Bold First Impression

The ProMag S&W M&P Shield 9mm 10 rd Black Finish – 9mm Caliber, 10 Rounds, Steel, Aftermarket Origin magazine promised to solve a persistent problem: expanding the capacity of my trusted M&P Shield without sacrificing reliability. Aftermarket magazines can be a gamble, but the promise of 10 rounds in a package only slightly larger than the original piqued my interest. This magazine immediately stands out with its black finish and claimed construction of heat-treated blued-steel and Technapolymer components.

My primary reason for seeking an alternative magazine was simple: more rounds offer peace of mind, especially for concealed carry. The standard 7 or 8 round capacity of the Shield felt limiting in certain scenarios. I’d considered similar options from Magpul and other manufacturers, but ProMag’s lower price point and relatively positive user reviews swayed my decision.

Upon receiving the ProMag magazine, my initial impression was one of cautious optimism. The blued-steel body felt sturdy, and the Technapolymer baseplate seemed reasonably durable. The weight was noticeably heavier than the stock magazine, a trade-off I expected for the increased capacity. Initial observations suggested a solid build, though only time and rounds downrange would truly reveal its quality.

Compared to the factory magazine, the ProMag offered a slightly extended grip, which felt more comfortable in my hand. However, the finish wasn’t quite as refined as the factory Smith & Wesson magazine, but for the price, it seemed acceptable. I was excited to test its reliability and performance, while also a little apprehensive about potential feeding issues common with aftermarket magazines.

Real-World Testing: Putting ProMag S&W M&P Shield 9mm 10 rd Black Finish – 9mm Caliber, 10 Rounds, Steel, Aftermarket Origin to the Test

First Use Experience

My first experience with the ProMag S&W M&P Shield 9mm 10 rd Black Finish – 9mm Caliber, 10 Rounds, Steel, Aftermarket Origin was at my local shooting range. I ran several drills involving rapid firing and reloads to assess its performance under pressure. The weather was mild and dry, providing ideal conditions for testing.

Initially, the magazine loaded smoothly and seated positively in my M&P Shield. However, I experienced a few failures to feed within the first 50 rounds. It seemed like the magazine spring was struggling to keep up with the slide’s speed, especially with the last few rounds.

Ease of use was generally good, but the slightly stiffer spring required a bit more effort when loading rounds manually. This was a little surprising considering the anti-fatigue spring claimed in the product description. After the first range session, I was cautiously optimistic but concerned about the early feeding issues.

Extended Use & Reliability

After several weeks and hundreds of rounds, the ProMag S&W M&P Shield 9mm 10 rd Black Finish – 9mm Caliber, 10 Rounds, Steel, Aftermarket Origin has proven to be a mixed bag. The initial feeding issues persisted intermittently, even after thoroughly cleaning and lubricating the magazine. Sometimes it ran flawlessly, other times it would choke on the last round or two.

Durability-wise, the magazine body and baseplate have held up well with only minor cosmetic wear. The blued-steel finish shows some slight scratches from repeated insertion and removal, but nothing alarming. Cleaning is straightforward; I simply disassemble it and wipe down the components with a solvent and lightly oil the spring.

Compared to my experience with factory Smith & Wesson magazines, the ProMag falls short in reliability. The factory magazines have been flawless, while the ProMag‘s occasional malfunctions make it unsuitable for serious defensive use in my opinion. While the increased capacity is nice, it’s not worth the risk of a potential malfunction in a critical situation.
