Are you looking to significantly enhance the capacity and reliability of your Smith & Wesson 9mm pistol? Do you frequently find yourself wishing for fewer reloads during range sessions, competitive events, or critical self-defense scenarios? For serious firearm enthusiasts, sport shooters, and responsible citizens, optimizing magazine capacity and ensuring flawless feeding are paramount. The MEC-GAR MGSW5920B 20-Round Extended Magazine for Smith & Wesson 659, 910, 915, and 5900 Series firearms is engineered precisely to meet these demands, offering an unparalleled blend of expanded capacity, robust construction, and legendary reliability.

This comprehensive guide delves into why the MGSW5920B stands out as a top-tier choice for upgrading your compatible S&W 9mm pistol. It addresses common questions about extended magazines, compatibility, and the proven quality that has made Mec-Gar a preferred OEM (Original Equipment Manufacturer) for countless firearm brands worldwide.

Unlocking Enhanced Capacity: What Does a 20-Round Magazine Offer?

The primary advantage of the MEC-GAR MGSW5920B is its impressive 20-round capacity. Compared to standard 10, 15, or 17-round magazines, an additional three to ten rounds can drastically alter your shooting experience and tactical preparedness.

Benefits of Increased Capacity:

• Extended Range Sessions: Spend more time shooting and less time reloading. This means more focused practice, improved shooting rhythm, and a more enjoyable day at the range.
• Competitive Edge: In disciplines where magazine capacity is permitted, having 20 rounds at your disposal can mean the difference between winning and losing. It reduces the need for costly and time-consuming reloads, allowing you to maintain focus on accuracy and speed.
• Heightened Self-Defense Capability: While local laws vary, a higher capacity magazine provides additional rounds for defensive situations, which can be critical for personal and home protection. It minimizes the need for a tactical reload under stress, offering peace of mind.
• Reduced Wear on Magazines: Owning multiple high-capacity magazines means rotating them during use, spreading wear and tear across your inventory and extending the overall lifespan of each magazine.

Designed for Flawless Compatibility: Smith & Wesson 9mm Series

The MEC-GAR MGSW5920B magazine is specifically engineered to provide perfect fit and function with a range of popular Smith & Wesson 9mm pistols. This precision compatibility is vital for ensuring reliable feeding and ejection, which are non-negotiable for any serious shooter.

Compatible Smith & Wesson 9mm Pistol Models:

This extended 20-round magazine is designed to seamlessly integrate with the following S&W 9mm Luger models:

• S&W Model 659: A popular second-generation semi-automatic pistol.
• S&W Model 910: Known for its value and reliability, part of the third-generation series.
• S&W Model 915: Another excellent third-generation pistol, often praised for its ergonomics.
• S&W 5900 Series: This broad category includes many widely used and respected pistols. Key models within this series for which the MGSW5920B is compatible include:
  • S&W 5903: Aluminum alloy frame.
  • S&W 5904: Aluminum alloy frame.
  • S&W 5906: All stainless steel construction, very common.
  • S&W 5946: Double-action-only (DAO) version of the 5906.
  • Other 59XX models: Generally, if your pistol is part of the 5900 series, this magazine should be a direct fit.

This extensive compatibility makes the MGSW5920B a versatile upgrade for a large segment of S&W 9mm pistol owners. Before purchasing, it is always recommended to double-check your specific firearm model to confirm compatibility.

The MEC-GAR Advantage: Quality, Reliability, and Durability

Mec-Gar is not just another aftermarket magazine manufacturer. With decades of experience, the Italian-based company has established itself as an industry leader, producing magazines for many of the world's most renowned firearm brands as an OEM supplier. This heritage translates directly into the quality and performance of every magazine they produce, including the MGSW5920B.

What Makes Mec-Gar Magazines Stand Out?

• OEM Proven Quality: Many major firearm manufacturers trust Mec-Gar to produce the magazines that ship with their new firearms. This speaks volumes about their manufacturing standards, material quality, and design precision. When you choose a Mec-Gar magazine, you are essentially getting an original equipment quality product, often at a more accessible price point than factory-branded equivalents.
• Superior Construction Materials: The MGSW5920B is constructed from high-quality heat-treated carbon steel. This robust material ensures exceptional durability and resistance to deformation, even under rigorous use. The steel body is less prone to cracking or deforming compared to some polymer-bodied magazines, especially around the feed lips.
• Blued Finish for Protection: The magazine features a classic blued finish. This traditional surface treatment provides excellent corrosion resistance, protecting the steel from rust and wear, extending the magazine's lifespan, and maintaining its aesthetic appeal. The bluing is applied with precision, ensuring even coverage and a smooth surface.
• Anti-Friction Coating: Internally, Mec-Gar magazines often feature a proprietary anti-friction coating. This crucial detail reduces the friction between the follower, the spring, and the magazine body, allowing for smoother, more consistent feeding of ammunition. It helps prevent jams and ensures reliable operation, even when the magazine is fully loaded.
• High-Performance Spring and Follower: The heart of any reliable magazine lies in its spring and follower. Mec-Gar utilizes high-tensile strength springs that resist "taking a set" over time, maintaining their tension for consistent feeding. The polymer follower is designed for optimal tilt resistance, ensuring rounds are presented correctly to the feed ramp with every cycle.
• Precision Engineering: Every dimension of the MGSW5920B is meticulously engineered to factory specifications. This attention to detail guarantees a precise fit within the magazine well, smooth insertion and ejection, and consistent feeding, minimizing the likelihood of malfunctions.

Real-World Applications and Scenarios

The MEC-GAR MGSW5920B is more than just a piece of metal; it's a performance enhancer for your S&W 9mm. Let's explore some scenarios where this extended magazine truly shines.

• For the Avid Target Shooter: Imagine the flow of a range session where you can fire 20 rounds before needing to reload. This continuous shooting helps in practicing faster target transitions, recoil management, and follow-up shots without interruption. It's ideal for drills that require multiple shots on target.
• For Competitive Shooters: In certain competitive divisions (e.g., USPSA Limited, IDPA Enhanced Service Pistol where rules allow), having a 20-round capacity means fewer reloads per stage, which translates directly to faster times and better scores. It allows competitors to focus purely on the stage design and their shooting technique.
• For Home Defense and Personal Protection: While magazine capacity laws vary by location, for those in jurisdictions where it's permitted, a 20-round magazine offers a significant advantage in a critical incident. It provides a greater margin of safety by reducing the chance of running dry during an encounter, potentially saving crucial seconds in a high-stress situation.
• As a Reliable Replacement: If your existing S&W 9mm magazines are old, worn out, or damaged, the MGSW5920B serves as an excellent, high-quality replacement or a valuable addition to your current magazine collection. It offers not just a replacement but an upgrade in capacity.
• For Law Enforcement or Security Professionals (where authorized): For those in tactical roles using compatible S&W 9mm pistols, extended capacity magazines provide a distinct operational advantage, reducing the frequency of reloads in dynamic environments.

Answering Your Key Questions About the MGSW5920B

Understanding the nuances of firearm accessories is crucial. Here are answers to common questions about the MEC-GAR MGSW5920B extended magazine:

Are Mec-Gar magazines reliable?

Absolutely. Mec-Gar is renowned globally for producing highly reliable magazines. Their reputation as an OEM supplier for major firearm brands speaks to their consistent quality control and engineering excellence. Many shooters consider Mec-Gar magazines to be on par with, or even superior to, factory original magazines in terms of performance and durability.

What Smith & Wesson models are specifically compatible with this magazine?

The MEC-GAR MGSW5920B is designed for the Smith & Wesson 9mm Luger 659, 910, 915, and the extensive 5900 Series pistols. This includes popular models like the 5903, 5904, 5906, and 5946, among others within the 59XX family.

What are the main benefits of an extended 20-round magazine?

The primary benefits include significantly increased ammunition capacity, leading to fewer reloads during training or competition, and an enhanced feeling of preparedness for self-defense scenarios. It can improve your overall shooting experience by allowing for longer strings of fire.

How does the blued finish protect the magazine?

The blued finish is a chemical treatment that creates a protective layer on the steel surface. This layer helps to prevent rust and corrosion, which can degrade the magazine's performance and lifespan, especially when exposed to moisture or humid environments. It also gives the magazine a classic, clean appearance.

Is a 20-round magazine practical for daily carry or concealed carry?

While some may choose to carry an extended magazine as a spare, a 20-round magazine, due to its increased length, is generally not practical for concealed carry in the firearm itself. Its extended base protrudes beyond the grip, making it less concealable. It excels in roles like range shooting, home defense, and open carry where concealment is not the primary concern.

Does the extended base plate affect grip or handling?

Yes, the MGSW5920B features an extended base plate to accommodate the increased internal spring length and capacity. This extension will protrude beyond the bottom of the pistol's grip. While some shooters might find it changes the feel, many appreciate the extended grip surface, particularly those with larger hands, which can enhance control and comfort during shooting.

Where can I find genuine Mec-Gar magazines?

Genuine Mec-Gar magazines, including the MGSW5920B, are available from reputable firearm accessory retailers. For the discerning shooter, the MEC-GAR MGSW5920B is readily available at DEGuns, ensuring you receive an authentic, high-quality product.

Maintaining Your Mec-Gar MGSW5920B Magazine

Proper maintenance ensures the longevity and reliable function of your magazine. Here are some essential tips:

• Regular Cleaning: Periodically disassemble the magazine (following safe procedures for handling springs) and clean out any dirt, carbon residue, or debris from the inside of the tube, the follower, and the spring. A clean magazine is a reliable magazine.
• Inspect for Wear: Check the feed lips for any signs of bending, cracking, or damage. Inspect the spring for any kinks, rust, or signs of weakness. Replace components if necessary.
• Avoid Over-Insertion: While robust, avoid forcefully slapping the magazine into the well, especially with the slide closed, as this can put undue stress on the feed lips and top round.
• Proper Storage: Store magazines unloaded if possible, or loaded but rotated regularly to prevent spring fatigue (though modern springs are highly resistant to this). Keep them in a dry environment to prevent rust.
• Lubrication (Minimal): Avoid excessive lubrication inside the magazine tube, as it can attract dirt and grime. A very light, dry lubricant or a silicone spray might be used sparingly on the spring and follower if desired, but often it's not necessary due to the anti-friction coating.

Conclusion: A Smart Investment for Your S&W 9mm

The MEC-GAR MGSW5920B 20-Round Extended Magazine is more than just an accessory; it's a strategic upgrade for your Smith & Wesson 9mm Luger 659, 910, 915, or 5900 Series pistol.
