Pearce Grip Magazine Extension Features The Pearce Grip Magazine Extension is molded from high impact resistant polymer that is tough and durable enough to operate across a wide temperature range from negative 20 to 350 degrees Fahrenheit. It replaces the factory base plate on compatible Springfield Hellcat Hellcat Pro and Taurus GX4/XL magazines adding one round of capacity in the process. The extension adds roughly 3/4 inch of additional gripping surface giving shooters more to hold onto for a firmer more controlled grip. Its Matte Black finish and textured pattern are designed to blend with the contour and texture of the pistol s own frame. This extension uses the patented PearceLock attachment mechanism to secure firmly to the magazine body without added tools or modification. It works on all magazine variants for these pistols except the Hellcat and Hellcat Pro 10 round magazines which are not compatible with this extension. On 13 round magazines the shooter gains the ergonomic benefit of the extended grip though factory +2 equipped magazines will not gain the extra round. This Pearce Grip Magazine Extension is available for sale at GrabAGun for Hellcat and GX4 owners looking to improve both capacity and grip.
