ProMag Polymer Taurus PT 99 9mm 50-Round Pistol Magazine Review

First Impressions of ProMag Polymer Taurus PT 99 9mm 50-Round Pistol Magazine

The ProMag Polymer Taurus PT 99 9mm 50-Round Pistol Magazine is a product that immediately sparks curiosity. High-capacity magazines promise extended shooting sessions and reduced reload times. But, the question always remains: can aftermarket magazines, especially those constructed of polymer, deliver the same reliability as factory originals?

I’ve spent countless hours on the range with my trusty Taurus PT 99, a firearm I’ve always appreciated for its ergonomics and accuracy. However, I’ve always been limited by the standard capacity magazines. The need for fewer reloads during training sessions and the slight edge in a hypothetical self-defense situation led me down the path of exploring high-capacity options.

Upon receiving the ProMag Polymer Taurus PT 99 9mm 50-Round Pistol Magazine, my first impression was mixed. The polymer construction felt lighter than the original metal magazines, which initially raised some concerns about durability. However, the overall design seemed robust, and the magazine seated firmly in the PT 99’s magwell.

Compared to a standard 15-round factory magazine, the ProMag offering is significantly longer. This is an expected trade-off for the increased capacity. I also considered other high-capacity magazines from different brands, but the ProMag’s aggressive price point and claimed reliability made it the first choice for testing.

My initial feeling was cautiously optimistic. The promise of 50 rounds of 9mm firepower in a single magazine was appealing, but I knew the true test would come at the range. Would it feed reliably? Would the polymer construction hold up under repeated use? Only time, and a few hundred rounds, would tell.


Real-World Testing: Putting ProMag Polymer Taurus PT 99 9mm 50-Round Pistol Magazine to the Test

First Use Experience

My first outing with the ProMag Polymer Taurus PT 99 9mm 50-Round Pistol Magazine was at my local outdoor shooting range. I wanted to gauge its performance in a relatively controlled environment. I loaded it with 50 rounds of standard 115-grain FMJ ammunition.

I experienced two failures to feed within the first 100 rounds. The rounds seemed to catch slightly on the feed ramp. After these initial hiccups, the magazine ran surprisingly smoothly for the next 50 rounds.

Extended Use & Reliability

After several weeks of use, including approximately 500 rounds through the ProMag Polymer Taurus PT 99 9mm 50-Round Pistol Magazine, I have a better understanding of its reliability. The magazine still experiences occasional failures to feed, roughly one every 50-75 rounds. This is more frequent than with the factory magazines.

The polymer construction has held up well, showing only minor wear marks around the feed lips. Cleaning is straightforward; I simply disassemble the magazine and wipe down the components. While the increased capacity is convenient, the occasional malfunctions make it less reliable than the factory magazines. It’s important to note the ProMag requires more frequent cleaning to maintain optimal performance.

Breaking Down the Features of ProMag Polymer Taurus PT 99 9mm 50-Round Pistol Magazine

Specifications

The ProMag Polymer Taurus PT 99 9mm 50-Round Pistol Magazine is specifically designed for the Taurus PT 99 platform. It’s chambered in 9mm Luger, ensuring compatibility with a wide range of ammunition. The most notable specification is its 50-round magazine capacity, providing significantly more firepower compared to standard magazines.

The magazine body is constructed from a DuPont Zytel-based polymer, offering a balance between weight and durability. The magazine spring is formed from heat-treated chrome silicon wire, designed to maintain consistent pressure and reliable feeding. The follower is injection molded, ensuring proper alignment and smooth movement within the magazine body. These specifications matter because they directly influence the magazine’s reliability, durability, and overall performance.

Performance & Functionality

The ProMag Polymer Taurus PT 99 9mm 50-Round Pistol Magazine delivers on its promise of increased capacity. However, its reliability is somewhat inconsistent. While it allows for extended shooting sessions without frequent reloads, the occasional failures to feed detract from its overall performance.

The magazine’s primary strength is its high capacity. A major weakness is its occasional unreliability. The magazine meets expectations in terms of capacity but falls short in terms of consistent feeding.

Design & Ergonomics

The ProMag Polymer Taurus PT 99 9mm 50-Round Pistol Magazine is designed to be compatible with the Taurus PT 99. The polymer construction keeps the weight relatively low for its size. The magazine seats firmly in the magwell.

The magazine’s extended length makes it less concealable than standard magazines. There isn’t a significant learning curve, although disassembly for cleaning can be slightly tricky due to the strong spring.

Durability & Maintenance

The polymer body of the ProMag Polymer Taurus PT 99 9mm 50-Round Pistol Magazine appears to be durable enough for regular use. However, I suspect it may not withstand the same level of abuse as a steel magazine. Regular cleaning is essential to maintain its function, especially the follower and feed lips.

Repairing the magazine is relatively simple; replacement springs and followers are readily available. However, replacing the entire magazine may be more cost-effective in some cases.

Accessories and Customization Options

The ProMag Polymer Taurus PT 99 9mm 50-Round Pistol Magazine does not come with any specific accessories. Due to its specific design for the Taurus PT 99, there are limited customization options beyond replacing internal components like the spring or follower. Aftermarket magazine pouches designed for high-capacity pistol magazines are compatible. While no accessories come with the magazine, it seamlessly fits into my existing PT99.

Who Should Buy ProMag Polymer Taurus PT 99 9mm 50-Round Pistol Magazine?

The ProMag Polymer Taurus PT 99 9mm 50-Round Pistol Magazine is perfect for recreational shooters who want extended range sessions without frequent reloads. It’s also suitable for those who prioritize high capacity over absolute reliability. This Magazine is a great fit for competitive shooters in certain divisions where high-capacity magazines are permitted.

This product is not ideal for individuals who require absolute reliability in self-defense situations. Those who prioritize concealability should skip this product due to its extended length. A must-have accessory would be a high-quality magazine pouch designed for extended magazines.

Conclusion on ProMag Polymer Taurus PT 99 9mm 50-Round Pistol Magazine

The ProMag Polymer Taurus PT 99 9mm 50-Round Pistol Magazine offers a compelling value proposition for Taurus PT 99 owners seeking increased firepower. While it delivers on its promise of high capacity, its occasional unreliability is a significant drawback. The affordable price makes it an attractive option for recreational use.

Whether the price is justified depends on individual needs and priorities. If you prioritize high capacity and are willing to accept occasional malfunctions, then the price is reasonable. I would recommend this product with reservations. I would recommend it for range use and training, but not for critical self-defense scenarios where absolute reliability is paramount.

Consider the ProMag, but be aware of its limitations and practice frequently to ensure familiarity with its performance.
