Description
If you own an M&P compact in 9mm or .40, you've probably noticed the size difference between your compact and full-size magazines. The X-Grip mag spacer bridges that gap so you can use your larger M&P 2.0 magazines without the awkward overhang or grip compromise. It slides right over the magazine and seats securely around the floorplate for a snag-free fit.
How the X-Grip Mag Spacer Works
The adapter is dead simple to install. Just slide it over your M&P 2.0 15-round magazine and you're done. No gunsmithing, no tools, no permanent modifications to your firearm. Once it's on, you get 3 additional rounds of capacity plus the hand support you'd get with a full-size grip. The design also acts as an over-insertion stop, which helps protect both your magazine and pistol frame from potential damage.
Grip and Control Benefits
Carrying a compact doesn't mean sacrificing ergonomics. The textured polymer matches the M&P grip pattern and fills the gap between the magazine baseplate and your hand, so you get a secure, full-hand hold instead of feeling pinched or cramped. This makes a real difference whether you're at the range or carrying for real use. Your pinky finger gets proper support rather than hanging in the air.
Material and Durability
Built from high-grade black polymer engineered to handle duty use, this adapter is made to last under field conditions. The design has been proven by military and law enforcement users across the country who rely on X-Grip products for mission-critical applications.

Frequently Asked Questions
Will this mag adapter work with my original M&P compact or only the 2.0 model?
This SWMPC2.0 model is designed specifically for S&W M&P 2.0 magazines and M&P Compact pistols. If you have an original (non-2.0) M&P Compact, you'll want the standard X-Grip adapter instead. Make sure you're pairing 2.0 magazines with this spacer for proper fitment.
Do I need to permanently modify my pistol to install this adapter?
No modifications required. The adapter slides directly onto your magazine and uses a drop-in design. No tools, no gunsmithing, no permanent changes to your firearm. If it doesn't work out, you can remove it just as easily.
How many extra rounds does the mag adapter add?
The X-Grip adds 3 rounds of capacity when used with M&P 2.0 15-round magazines on your compact pistol. The spacer itself doesn't hold ammunition—it just fills the gap so you can comfortably use the full-size magazine with your compact frame.
Will the mag spacer affect how easily I can draw and reload?
The spacer creates a snag-free fit that seats securely around the floorplate, so it won't catch on your holster or clothing. It's designed to integrate seamlessly with your M&P's lines. Some users report they pair it with grip tape on the magazine for extra friction if they ever need to grab the mag by the adapter itself.
