Pachmayr's Mag Sleeve adapts full-size magazines for use with compact handguns in many popular models. The sleeve allows 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 Mag Sleeve when the situation calls for it. This model is compatible with your Glock 29. Our Mag Sleeves simply slide over the magazine and fit securely in place. Improve your handling and performance of compact handguns such as the S&W, Colt & Para Models with Pachmayr Mag Sleeves.
