Owners of the Charter Arms Undercover like the small size and light carry weight for pocket or ankle use, and the .38 Special chambering keeps recoil manageable in a gun this compact. The double-action trigger pull is a common complaint: several owners describe it as heavier or grittier than a comparable revolver from a bigger-name maker, though most say it smooths out with use.

Build quality opinions are split. Most owners find the stainless finish holds up fine to daily carry and the occasional rain, and the gun runs reliably as a backup or primary concealed carry piece. A smaller number report fit and finish issues out of the box, like a stiff cylinder release or minor machining marks.

For the money, most buyers see the Undercover as solid value next to premium-brand five-shot revolvers, and the fixed sights and simple controls suit its role as a no-frills carry gun rather than a range toy.
