Frequently Asked Questions
Will this extension work with my M&P 2.0 pistol?
The Shield Arms +5 extension is designed specifically for Smith & Wesson M&P 2.0 Full-Size and Compact models. It works with M&P 2.0 OEM factory magazines. If you have an M&P M2.0 model (the updated version), this extension is compatible. It is not designed for original M&P models (pre-2.0) or M&P Shield pistols.
How difficult is installation?
Installation is straightforward and takes just a few minutes per magazine. The extension includes all necessary hardware and allen wrenches. Simply disassemble your magazine, remove the factory basepad, install the Shield Arms extension with the provided longer spring and follower components, and reassemble. No permanent modifications are required. For detailed guidance, visit our installation guides page.
Does adding 5 rounds affect magazine reliability?
No. Shield Arms extensions are precision-engineered to maintain factory-level reliability. The extension works with an extended spring system that maintains proper tension throughout the increased capacity. Each design is extensively tested with various ammunition types to ensure consistent feeding. Thousands of competitive shooters and law enforcement professionals trust Shield Arms extensions for duty and competition use.
Will this extension fit in my pistol's magazine well?
Yes. The Shield Arms M&P 2.0 extension maintains the same external width as your standard magazine, so it feeds and locks into your pistol normally. The extension only adds length to the bottom of the magazine to accommodate the additional rounds. Your pistol will function exactly as it does with standard magazines.
Can I use this extension in USPSA or IDPA competition?
Yes, depending on your division. In USPSA, the extended capacity magazines are legal for Limited, Open, and Production Optics divisions. For IDPA, check your specific division rules as some limit magazine capacity. Many competitive shooters use Shield Arms extensions in divisions where higher capacity magazines provide an advantage by reducing reload frequency.
What's the difference between this and the pre-installed version?
This product is the extension kit that you install on your existing M&P 2.0 magazines. The M&P 2.0 Pre-installed Extension comes as a complete magazine with the extension already professionally installed and tested. Choose the kit if you want to extend your current magazines; choose the pre-installed version if you want ready-to-use extended magazines.
Does the extension add significant weight to the magazine?
The aluminum construction keeps weight minimal. While you will add the weight of 5 additional rounds when fully loaded, the extension itself is lightweight and won't significantly affect your pistol's balance or handling. The aircraft-grade aluminum provides exceptional strength without unnecessary bulk.
Are these extensions legal in my state?
Magazine capacity laws vary by state and locality. Some states restrict magazine capacity to 10 rounds or less, which would make this extension non-compliant in those jurisdictions. It is your responsibility to know and follow all federal, state, and local laws regarding magazine capacity. Shield Arms does not ship products to addresses in states where they are prohibited.
What is covered under the warranty?
All Shield Arms magazine extensions are covered by our 100% lifetime warranty against defects in materials and workmanship. Additionally, our "Spring for Life" guarantee ensures that if your magazine spring ever wears out or loses tension, we'll replace it free of charge for as long as you own the product.
Can I remove the extension if needed?
Yes. The Shield Arms extension installs without permanent modifications, so you can return your magazine to standard configuration at any time. This makes it ideal for shooters who need to switch between extended and standard capacity based on their application or location.
Will this work with aftermarket M&P magazines?
This extension is designed and tested specifically for Smith & Wesson M&P 2.0 OEM factory magazines. While it may physically fit some aftermarket magazines, we can only guarantee proper function and reliability with genuine S&W magazines. Using the extension with non-OEM magazines may result in feeding issues or improper fit.
How does this compare to other magazine extensions on the market?
Shield Arms extensions are precision CNC-machined from aircraft-grade aluminum rather than polymer or stamped metal. This provides superior durability and dimensional consistency. Our M&P-specific engineering ensures proper geometry for reliable feeding, and every extension is made in the USA with rigorous quality control. Combined with our lifetime warranty and Spring for Life guarantee, Shield Arms delivers premium quality and value.
Installation & Setup
Installing your Shield Arms M&P 2.0 +5 Magazine Extension is a straightforward process that takes just minutes per magazine.
