Owners of the Glock 42 consistently point to Glock's reputation for reliability, and this model tends to run without complaint across different types of .380 ACP ammunition. The Safe Action trigger system is familiar to anyone who has used other Glock pistols, and most owners find the lack of a manual safety intuitive rather than concerning.

As a compact carry pistol, the Glock 42 draws praise for how easily it disappears in a pocket or waistband holster. Some shooters with larger hands find the grip a bit short for a completely secure hold, and recoil in .380 ACP is generally described as mild compared to larger-caliber compacts.

Aftermarket support is strong given Glock's popularity, with holsters, sights, and grip accessories widely available. Novelty finishes like the Diamond glitter coating are a matter of personal taste, some owners like the distinctive look while others prefer a plain factory finish, but it does not change how the pistol runs.
