Our Assessment: This Gemtech TSS Oasis represents a purpose-built integrally suppressed rimfire Ruger style receiver developed during the period when dedicated suppressed handguns were gaining traction among professionals and serious recreational users. Built around the Ruger Mk. II & Mk. III platform, the Oasis was engineered as a complete system rather than a host-and-threaded suppressor combination, with the suppressor tube and baffle stack integrated into the 7.5-inch total barrel/receiver assembly. This results in a clean, compact, and well-handling suppressed pistol that reflects Gemtech’s reputation as one of the early leaders in commercial sound suppression. Chambered in .22 Long Rifle, the platform is ideally suited to integral suppression, combining low recoil, cheap ammo, and excellent inherent accuracy. This example remains in excellent overall condition, retaining approximately 99 percent of its finish with only faint operational wear noted on the bolt and action. The bore is bright with sharp rifling and no erosion, rating 9.5 out of 10, while the internal baffles show moderate carbon buildup consistent with normal use rather than neglect. The Truglo fiber-optic front sight and adjustable rear sight remain crisp and well aligned, supporting precise aiming even in low-light conditions.
The Ruger 22/45 grip frame provides familiar ergonomics with molded checkering and a lightweight polymer construction, showing only light handling marks and no structural issues. Markings remain clear and legible throughout, and the pistol includes its correct magazine, factory paperwork, and padded hard case. As an integrally suppressed rimfire pistol from a respected manufacturer, the TSS Oasis stands as a refined and increasingly uncommon example of a dedicated suppressed handgun system, valued for its cohesive design, excellent condition, and representative role in the evolution of modern rimfire suppression.
