Pachmayr Grip Extenders adapt full-size magazines for use with compact handguns in many popular models. Grip Extenders allow you greater shooting capability by increasing the gun's grip size and capacity with additional rounds. Carry your compact pistol with a standard magazine when concealment is important, or insert a high capacity magazine fitted with your Pachmayr Grip Extender when the situation calls for it. Pachmayr grip extenders simply slide over the magazine and fit securely in place. Note: Designed for the standard capacity 17 round mag body
