Ruger Mark IV Hunter 40177 .22 LR 5.5" Fluted 10+1 TALO

Description

The Ruger Mark IV Hunter Model 40177 is a TALO Distributor Exclusive .22 LR semi-automatic pistol combining the Mark IV platform with a distinctive 5.50-inch fluted bull barrel, blued alloy-steel construction, checkered hardwood grips, fiber-optic front sight, adjustable rear sight, and 10+1 capacity. Ruger identifies this exact configuration as Model 40177 / UPC 736676401772 and currently lists it as having limited availability.

The defining characteristics of Model 40177 are its fluted bull barrel and hardwood grips. The 5.50-inch cold hammer-forged barrel combines the rigidity of a bull-barrel profile with fluting that gives the pistol the distinctive appearance associated with Ruger’s Hunter series. It uses six grooves and a 1:16" right-hand twist.

Unlike the more common stainless Mark IV Hunter configurations, Model 40177 is finished in blued alloy steel. Ruger pairs the blued upper with a precision CNC-machined aluminum grip frame and checkered hardwood grip panels, making the finish and grip combination particularly important when distinguishing this TALO-exclusive SKU.

The pistol is chambered in .22 Long Rifle with a factory capacity of 10+1 rounds. Ruger includes two 10-round magazines and a hard plastic case. The push-button magazine release is located on the left side of the frame, and the magazines are designed to drop free when released.

For sights, Model 40177 features a highly visible fiber-optic front sight paired with an adjustable rear sight. The receiver is also drilled and tapped for a Weaver- or Picatinny-style rail, allowing compatible optics to be installed with the appropriate mounting rail.

A major feature of the Mark IV platform is Ruger’s one-button takedown system. Pressing the recessed button at the rear of the frame allows the barrel-receiver assembly to tilt upward and separate from the grip frame without tools, greatly simplifying field stripping and chamber-to-muzzle cleaning.

The Mark IV uses an internal cylindrical bolt rather than a conventional reciprocating slide. Ruger notes that this construction maintains permanent sight-to-barrel alignment, contributing to the platform's accuracy potential. The pistol also features easy-to-grasp bolt ears and a contoured ejection port.

Safety equipment includes an ambidextrous manual safety, which can be converted to left-side-only operation with the included washer, and a magazine disconnect that prevents the pistol from firing when the magazine is removed.

Model 40177 weighs 35.6 ounces and measures 9.75 inches overall, 5.50 inches high, and 1.20 inches wide. Ruger lists this TALO-exclusive configuration as not approved for California or Massachusetts.
