Owners of Charter Arms revolvers in this class typically value the lightweight build and the compact 2-inch format for everyday carry. The Blue Diamond off-duty configuration appeals to those who want a simple, snag-free double-action-only draw with minimal controls to manage.

The trigger on Charter Arms revolvers draws divided opinions. Some find the double-action-only pull smooth enough after break-in, while others find the pull weight heavier than comparable snub-nosed revolvers. The 5-round cylinder is a common point of discussion among those who prefer higher-capacity options.

Build quality perception varies by price point. Charter Arms sits in the budget-to-mid-range segment, and owners generally find the revolvers functional and reliable for carry, though finish quality and tolerances are sometimes noted as inconsistent compared to higher-priced alternatives.
