The Hornady in the Cor-Bon DPX both experienced one failure to feed out of the total of 20 rounds. The other premium brands and 150 rounds of the ball ammunition fed through the pistol flawlessly. I’ve seen other reviews that indicated there are some rounds that this pistol doesn’t like; however, the copy I have really was not that picky. Of course 20 rounds is insufficient to base your life on a particular brand; however, I believe that it will not be that difficult to find a self-defense round that provides typical GLOCK performance and reliability.
The Glock 42 is a small, easily concealable pistol that’s designed to be carried. That said, it’s also a little larger than a lot of other .380 options out there (e.g., the Kel Tec, Ruger, SIG, Kahr). It will go into a pocket holster if your pants pockets are large enough. Holster carry on the belt should be very comfortable. I’ve carried a SIG P238 in a holster for years—it’s easy to forget it’s on your belt. I expect no less from the little 42.
For shooters with smaller hands, the G42 feels ideal. Like the SIG P238, having real, useable sights on a .380 is a nice addition. The stout trigger pull did not seem to be a hindrance to reasonably accurate shooting. At 10 yards standing, shooting 10 rounds, the Hornady Critical Defense produced a 2-inch group, the Winchester Supreme Elite produced a 3-inch group, the Cor Bon DPX a 2-inch group, the Speer Gold Dot a 3-inch group, and the Magtech a 3-inch group.
I believe that Glock 42 to be a worthy addition to the Glock line-up. It was accurate, reliable, and pleasant to shoot.
