The original thumbsnap holster, designed by Bianchi more than 30 years ago, this holster design has proven itself for carrying long barreled revolvers in the field, and is equally adept in concealment applications. An integral steel-reinforced thumb snap secures the gun and prevents the hammer spur from snagging on clothing. All sizes fit 1-3/4 belts, while the 4 and 6 barrel lengths also accommodate belts up to 2-1/4.
