The ProMag PM089A is a grip spacer that enables Glock 17/22 magazines to function in Glock 26/27 pistols. The spacer fills the gap between the pistol frame and the floor plate of the longer magazines, securing with a single Allen-head cap-screw. Its textured surface matches standard Glock pistol frame finishes. Construction is injection-molded polymer in black.
NOTE: This item is not compatible with Gen 4 Glock pistols.
