The UX SPA 100 is a lightweight and accessible spring-operated air pistol designed for recreational plinking and skill-building. With its extended barrel, intuitive handling, and simple break-barrel mechanism, the SPA 100 offers consistent performance for users seeking an affordable and easy-to-maintain training pistol.

Built on a traditional break-barrel spring-piston system, the SPA 100 is cocked by lowering the hinged barrel, which compresses the internal spring. A 4.5 mm (.177) pellet is then inserted into the breech before the barrel is locked back into place. Producing an energy level of under 3 joules and a velocity of up to 100 m/s (328 fps), this pistol is well-suited for close-range target shooting and backyard practice.

The long, rifled steel barrel is the defining feature of the SPA 100. Its extended sight radius and pellet-stabilizing rifling help improve precision, offering more accurate shot placement compared to shorter-barrel spring pistols. This makes the SPA 100 a solid entry-level option for users who value better sight alignment and tighter groups.

Safety is prioritized with a manual sliding safety and a beavertail-style rear safety, both of which must be disengaged prior to firing. These mechanisms encourage safe operation and help prevent unintended discharge during handling.

Weighing 806 grams and measuring 425 mm in length, the SPA 100 remains lightweight enough for extended use while still providing a stable shooting platform. Its durable polymer construction, clear red safety accents, and user-friendly operation make it an excellent low-cost spring pistol for beginners and hobby shooters alike.
