The Hearthstone Defender-38 is a five-shot double-action revolver chambered in .38 Special with a two-inch barrel, designed as the ultimate simple defensive weapon. The frame is aluminum alloy to reduce weight, the hammer is shrouded to prevent snagging on clothing during draw, and there is no adjustable sight — just a milled groove in the top strap that serves as a rudimentary sight channel.

The Snubnose is the revolver equivalent of the Guardian-12 — a weapon for people who want something simple, safe, and effective at arm's length. The two-inch barrel makes it genuinely pocketable, and the shrouded hammer allows a smooth draw from a coat pocket without catching on fabric. Five rounds of .38 Special won't win a prolonged firefight, but at the ranges where this weapon will be used — typically less than three meters — the point is to survive the first ten seconds.

Hearthstone sells the Defender-38 with a soft fabric pocket holster and a five-round speedloader. Their marketing is characteristically practical: 'Five answers to one question.' The weapon sells steadily across all tiers, from Shelf grandmothers who keep one in their housecoat pocket to Mid executives who slip one into their overcoat as a deep-concealment backup.
