Pachmayr Gun Works 03884: Pachmayr s new Grip Extenders will greatly increase your control and shooting comfort when added to popular compact and sub-compact handguns. The extensions perfectly match the shape and texture of the handgun, so they look like they are part of the pistol, rather than an add-on. Extenders are easy to install and are made of tough, high strength polymer that stands up to the roughest handling.
