Glock G42 Gen3 | .380 ACP | 6-Round | UI4250201

The Glock G42 Gen3 is a slimline subcompact pistol in .380 ACP designed for deep concealment and easy carry. It uses Glock’s Safe Action system within a black polymer frame and ships with two 6-round magazines. The pistol’s fixed sights and small footprint make it well suited to pocket or appendix carry and to shooters who prefer a single-stack compact platform.

A compact red-dot such as a Trijicon RMR or a Holosun 407K is a good optic choice under $1,000 for low-profile, close-range aiming on micro pistols; note the G42 is not drilled and tapped factory‑standard, so mounting an optic may require slide modification or an aftermarket mounting solution.
