In the right hands, the Glock 42 pistol could conceivably become as deadly as its larger caliber brethren. The smallest Glock, it is also suitable for whom concealability is a major purchase factor. While not for everyone, the combination of Glock’s pistol platform and John Browning’s small automatic caliber is still a compelling choice for users who combine both skill and discretion.A combination of the successful Glock pistol design and a caliber invented by armsman John Moses Browning, the Glock 42 is certainly worth taking a look at.The pistol combines the Austrian gun manufacturer’s gun operating system with the .380 ACP pistol cartridge. The result is both a pistol for concealed carriers who desire a low recoil pistol and the smallest pistol in Glock’s lineup.(This first appeared in early June.)Austrian gun manufacturer Glock has taken a tree-like approach to its pistol lineup, with the original Glock 17 9-millimeter pistol the trunk each major caliber it forays into a branch. The company will typically introduce the full-sized Glock in a new caliber, then quickly follow with compact, sub-compact, and competition-sized pistols to round out the caliber offering.Unlike other branches, like the .45 ACP and the .40 Smith & Wesson, the .380 ACP branch of the Glock tree is the smallest of them all, consisting of a single pistol: the Glock 42. The smallest and least powerful of all calibers the company has endorsed, the nature of the .380 ACP round makes it only suitable for a modern subcompact design.
