Analysis

The Glock 42 shares consistent mechanics in a slim single-stack layout, demonstrating reliable durability in civilian concealed carry and backup roles worldwide. Major components support aftermarket options and parts availability specific to the G42 platform, with the reversible magazine catch enabling left- or right-hand use and the dual recoil spring assembly aiding in managing the cartridge's mild recoil. Early production examples featured polygonal rifling, while pistols manufactured from approximately 2017 onward incorporated the Glock Marksman Barrel with conventional rifling and a revised crown. The polygonal rifling supports reliable function with typical .380 ACP ammunition and contributes to consistent practical accuracy at defensive distances. The subcompact dimensions and 6-round standard capacity (expandable via extended magazines) provide a balance of concealability and reduced grip width compared to double-stack subcompacts, while the Gen4 ergonomics offer a familiar handling feel without finger grooves. The .380 ACP chambering produces low recoil suitable for smaller-framed shooters, though capacity remains lower than higher-caliber subcompacts. Secondary market preferences depend primarily on condition, originality, remaining finish, and individual grip fit rather than any inherent differences in mechanical performance or durability relative to other subcompact models.

Great BABY!

This is a great little gun! I usually carry “9’s” but this thing is so light and concealable I find myself carrying it quite often with a “STICKY” pocket holster. I don’t necessarily agree that a 9mm is much better. .380 ammo has come a long way and WOULD NOT want to be shot by my GLOCK 42! This is actually a great gun for people that are a little intimidated to carry, especially the ladies.

Well made 380 designed for concealed carry. So light you forget you're carrying it. Experienced failures when limp wristing but totally reliable otherwise. Recoil is moderately snappy for inexperienced shooters. Really accurate up to 10 yards...I don't shoot it any farther than that. About 400 rounds so far.
