Bryant Ridge's Analysis:
The High Standard Sentinel MK IV is a strikingly distinctive revolver in the company’s lineup, representing a departure from the lightweight aluminum-framed rimfire Sentinels and stepping boldly into centerfire territory with a robust, full-sized design that feels significantly more serious in the hand. Produced in the late 1960s and early 1970s, the MK IV is chambered in .357 Magnum, giving it the power and versatility to serve as a defensive handgun, field companion, or range revolver, and High Standard engineered the frame and lockwork accordingly—substantially strengthening the topstrap, cylinder, and internals compared to their rimfire predecessors. The revolver’s lines remain unmistakably “Sentinel,” with a scalloped, streamlined frame, wraparound grip frame, and a slightly futuristic profile that differs sharply from traditional Smith & Wesson or Colt silhouettes; this gives the MK IV a visual identity few revolvers of its time can match. Usually finished in a deep, polished blue, it pairs rugged construction with a clean, refined aesthetic, while its contoured, checkered grips provide a stable hold even when firing full-house .357 loads. The six-shot cylinder locks up with surprising solidity, and the trigger—both double-action and single-action—tends to be smoother than expected for a design not derived from the classic American DA lineage, giving the gun a pleasantly controllable character on the range. Sights are practical and straightforward: a fixed rear notch paired with a prominent ramp front, well-suited to defensive or general-purpose shooting.

Though the MK IV was not produced in large numbers and never achieved the commercial success of the big revolver manufacturers, that limited production has made it increasingly interesting to collectors today, who appreciate its unusual design, strong construction, and the sense of experimentation it embodies. As a shooter, the Sentinel MK IV provides a surprisingly refined experience wrapped in a unique, underrated package—High Standard’s bold attempt to build a competitive mid-20th-century magnum revolver with a character all its own.
