SIG SAUER Magazine P938 9 mm, 7 Round Review

What You Didn’t Know About the SIG SAUER Magazine P938 9 mm, 7 Round

When looking to enhance the reliability and capacity of my concealed carry firearm, the SIG SAUER Magazine P938 9 mm, 7 Round became a focal point. My Sig Sauer P938, a compact and capable pistol, felt slightly limited by its standard magazine capacity during extended range sessions or when prioritizing defensive readiness. The allure of an additional round and a more substantial grip extension was undeniable. I’d previously experimented with some aftermarket options, but the nagging desire for guaranteed factory performance and a perfect fit led me back to the OEM solution. Upon receiving this magazine, my first impression was positive; the SIG SAUER branding promised quality, and the heft of the steel construction felt robust. It’s a simple part, a magazine, but its impact on the user experience is significant. The initial thought was simply, “This should just work flawlessly.”

Real-World Testing: Putting SIG SAUER Magazine P938 9 mm, 7 Round to the Test

First Use Experience

My initial testing of the SIG SAUER Magazine P938 9 mm, 7 Round took place at my local indoor shooting range, a controlled environment ideal for assessing magazine feeding and seating. I loaded it with various types of 9mm ammunition, from range fodder to defensive rounds, to ensure broad compatibility. The magazine seated with a satisfying click, and the additional length provided a welcome extension for my pinky finger, improving my grip considerably.

During the first few magazines, I paid close attention to every round fed from the P938 magazine. There were no failures to feed, no malfunctions, and each cycle felt smooth and consistent. The extended baseplate also proved beneficial, providing a more positive grip during tactical reloads, though initially, I was wary of it snagging.

Extended Use & Reliability

Over several months, this 7-round magazine has become a staple in my range bag and often resides in my P938 for concealed carry. I’ve subjected it to hundreds of rounds, including numerous simulated emergency reloads where I intentionally dropped the magazine to mimic a real-world scenario. This is where I encountered its most significant weakness.

The baseplate, while offering a good grip, can indeed become dislodged during forceful magazine drops, particularly if it hits a hard surface. This happened more than once, requiring me to re-seat the baseplate before the magazine could be properly inserted into the firearm. This was a surprising and potentially problematic issue for a critical piece of equipment.

Despite this, the internal mechanism of the magazine has held up exceptionally well. The spring remains strong, consistently pushing the last round up with authority, and I’ve experienced no significant wear on the feed lips. Cleaning is straightforward; a simple wipe-down and occasional light lubrication suffice. Compared to some aftermarket magazines that can develop stiffness or feeding issues after heavy use, the OEM SIG SAUER offering, even with its baseplate caveat, has demonstrated superior long-term reliability in terms of feeding.

Breaking Down the Features of SIG SAUER Magazine P938 9 mm, 7 Round

Specifications

The SIG SAUER Magazine P938 9 mm, 7 Round is constructed primarily from durable Steel, a material chosen for its strength and longevity in firearm components. It’s chambered for the 9 mm Luger caliber and boasts a 7 Round capacity. The magazine comes in a standard Black finish, designed to complement the aesthetic of the Sig Sauer P938 pistol. Its dimensions are specifically engineered for the P938 model, ensuring a precise and secure fit.

This capacity increase offers a significant advantage over the flush-fit magazines, providing an extra round of ammunition ready for deployment. The steel construction is a critical factor in its reliability, ensuring it can withstand the pressures and stresses of repeated use without deforming. The black finish is not only aesthetically pleasing but also offers a degree of corrosion resistance, though it’s primarily the underlying steel that provides the bulk of its durability.

Performance & Functionality

The core function of any magazine is to reliably feed ammunition into the firearm, and in this regard, the SIG SAUER Magazine P938 9 mm, 7 Round generally excels. I have encountered zero feeding issues with a wide variety of ammunition types, from standard ball to premium defensive rounds. The last round always presents correctly, without any tendency to hang up or misfeed.

However, its primary functional weakness lies in the security of its baseplate during aggressive handling or drops. While it provides a helpful grip extension, the rear of the baseplate is susceptible to sliding upwards, preventing the magazine from seating fully if it impacts a hard surface. This has, on occasion, led to the magazine dropping free during recoil after a reload attempt. This issue is a notable detraction from an otherwise stellar performance profile.

Design & Ergonomics

The design of the SIG SAUER P938 magazine is a clever balance between enhanced functionality and compact form factor. The extended baseplate is the most striking ergonomic feature, providing that crucial bit of real estate for the pinky finger. This significantly improves the grip on the otherwise small P938, making it feel more secure and controllable, especially for those with larger hands.

The overall build quality is excellent, with smooth edges and precise tolerances. The spring mechanism operates with a satisfying tension, and the follower moves freely within the magazine body. The steel construction feels solid and well-finished, giving confidence in its longevity.

Durability & Maintenance

In terms of internal durability, the SIG SAUER Magazine P938 9 mm, 7 Round is a champion. The steel body and robust internal spring have shown no signs of wear or reduced performance even after hundreds of cycles. Maintenance is exceptionally simple; a quick field strip of the magazine, wiping down the components, and reassembly is all that’s typically needed.

The potential durability concern, as noted, lies with the extended baseplate. While the mechanical connection to the magazine body is generally secure, it’s not as robust as a permanently affixed or screw-secured baseplate. This design choice prioritizes a sleek look and ease of assembly over absolute impact resistance. Over time, this could potentially lead to a loosening or even detachment if frequently dropped on hard surfaces.

Accessories and Customization Options

This particular SIG SAUER Magazine P938 9 mm, 7 Round comes as a standalone unit, with no additional accessories included. It is an OEM (Original Equipment Manufacturer) part, meaning it’s designed to integrate seamlessly with the Sig Sauer P938 pistol without requiring any modifications. There are no customization options inherently built into the magazine itself, such as interchangeable baseplates from the factory.

While not an accessory for the magazine, it’s worth noting that pairing this with a quality magazine pouch designed for a 7-round P938 magazine will ensure it’s readily accessible and securely held during concealed carry. The extended baseplate may necessitate a slightly deeper pouch than flush-fit magazines.

Pros and Cons of SIG SAUER Magazine P938 9 mm, 7 Round

Who Should Buy SIG SAUER Magazine P938 9 mm, 7 Round?

This SIG SAUER Magazine P938 9 mm, 7 Round is an excellent choice for owners of the Sig Sauer P938 who are looking to optimize their firearm for concealed carry or range use. If you find the standard grip of the P938 a bit too small for your liking, especially for your pinky finger, this magazine is a game-changer. It’s ideal for those who prioritize reliability and a perfect fit above all else, and who are willing to invest in genuine SIG SAUER quality.

However, individuals who frequently train with magazine drops on concrete or other unforgiving surfaces might want to consider aftermarket baseplates designed for increased impact resistance or simply exercise extreme caution during reloads. Those on a very tight budget might find cheaper aftermarket alternatives, but they risk sacrificing the guaranteed fit and reliability of this OEM component. A good quality magazine pouch is a wise companion accessory to ensure this magazine is always ready when you are.

Conclusion on SIG SAUER Magazine P938 9 mm, 7 Round

The SIG SAUER Magazine P938 9 mm, 7 Round is, for the most part, a superb upgrade for the Sig Sauer P938 pistol. It delivers on its promise of enhanced grip, increased capacity, and rock-solid reliability in terms of feeding. The steel construction and perfect OEM fit inspire confidence, making it a worthwhile investment for any P938 owner seeking a more comfortable and capable shooting experience.

The primary drawback, the potential for the baseplate to dislodge on impact, is a real concern that owners must be aware of. However, for many users who don’t routinely slam magazines onto hard surfaces, this might be a minor inconvenience compared to the significant ergonomic and functional benefits it provides. Considering its price and the quality of SIG SAUER manufacturing, it represents a solid value proposition for those who can accept or mitigate its one notable flaw. I would recommend this magazine, particularly for those who prioritize a better grip and an extra round for their P938, but with a clear understanding of its limitations during aggressive handling.
