xs sights has added a magazine extension to its lineup, and before you write this off as just another aftermarket add-on, it’s worth understanding the approach here. Most extensions at this price point either require a spring swap to function reliably with additional capacity, or they do not function reliably at all. XS specifically engineered the +5 to work with the factory springs on both the S&W M&P 2.0 and Walther PDP without any component changes. This means the install is truly plug and play, no tools, no advanced internal parts, no extra trips to the parts counter.

The extension is crafted from aircraft-grade aluminum and finished in black nitride, giving it better corrosion and wear resistance than standard anodizing. The fit is precision machined to integrate with factory magazines rather than relying on set screws or friction, and the extra length of the extension provides a slightly longer grip surface as a secondary benefit for shooters who run these pistols in competition or duty use.
- Capacity increase: +5 rounds
- Material: Aircraft-grade aluminum
- Finish: Black Nitride
- Installation: Tool-free
- Spring Requirement: Factory Spring compatible, no upgrade required
- Compatible: S&W M&P 2.0 (15-round and 18-round magazines), Walther PDP (15-round and 18-round magazines)
- Warranty: Limited Lifetime
- MSRP: $40.00
Compatibility covers both 15-round and 18-round factory magazine variants on each platform, so if you’re running both the compact and full-size versions you’re covered with the same extensions. At $40 it’s a low-risk upgrade for those who want more rounds in the gun for competition stage planning, training or defensive use without purchasing entirely new magazines.
The XS supports the extension with its Limited Lifetime Warranty, which adds value on a component that gets a lot of use and abuse in any hard-use pistol setup.
