Owners of the North American Arms Mini-Revolver line treat the Iris largely as a carry piece or novelty, and opinions split along those lines. Those who carry it appreciate how small and light it is, though the .22 Magnum ported barrel makes a surprisingly sharp report for the size.

The single-action mechanism requires deliberate thumb-cocking, which some find reassuring as a safety feature and others find slow under stress. The faux white pearl grips and turquoise Cerakote are polarizing; buyers who want the look are pleased, and those expecting a purely utilitarian tool are sometimes caught off guard.

Reliability feedback is generally positive for a rimfire revolver of this class. The common complaint is that the sights are minimal and the small frame limits practical accuracy beyond a few yards, which most owners accept as a trade-off for the size.
