GUN OF THE DAY - Cutaway Glock Pistol. Our polymer presentation is a little lighter than some others as this pistol is an actual factory cutaway, sectionalized to illustrate the internal components and their functioning. For armorers, or arms students, seeing "inside" the action of a handgun can reveal how parts fit together and other details. For collectors, these factory made cutaways are not often encountered on the market. Caliber: 9mm. Production Date: 1988.
