This Thunder 45 Ultra Compact is the earlier pre-"Pro" configuration, chambered in .45 ACP and sized for concealability without giving up capacity. It uses a 3.6-inch barrel and holds 7+1 rounds, with overall dimensions of approximately 6.81 inches in length, 5.08 inches in height, and 1.46 inches in width. Unloaded weight is about 27 ounces.
The pistol operates on a Browning-type linkless short-recoil system with a traditional DA/SA trigger. Controls include an ambidextrous manual safety/decocker and a left-side magazine release. An automatic firing-pin safety and an external spur hammer round out the control and safety features.
Sight picture is provided by fixed 3-dot sights: a front blade with a white dot and a dovetailed, notched rear with two white dots. The slide has rear serrations for traction. The frontstrap and backstrap feature vertical grasping grooves, and the black wrap-around textured grips with the BERSA logo offer a secure hold. The included magazine has a finger-rest baseplate for added purchase.
Built with an alloy frame/receiver, this compact .45 is marked "IMPORTED BY RSA ENTERPRISES INC. OCEAN N.J." and was made in Argentina. The slide and frame have matching serial numbers, aligning with the factory configuration and import documentation.
