The Mustang is a true micro 1911-style pistol with single-action-only operation and an external rowel-style hammer. It incorporates Series 80 safety engineering with a firing pin block and a manual thumb safety, along with a push-button magazine release and a 6+1 capacity in .380 ACP.
The slide features rear cocking serrations and polished/brushed flats contrasted by a matte top, set over a matte dark frame. Sights are fixed, with a ramped front and a square-notch rear, matching the original Mustang configuration.
Its bushingless barrel arrangement includes an exposed recoil spring plug at the muzzle, a hallmark of the Mustang design that contributes to its compact profile. The standard short-grip format identifies this example as the classic Mustang variant (not Plus II or Pocketlite).
Made in the United States in 1988, this pistol aligns with the Mustang’s MU-prefix serial range, placing it squarely in the late-1980s production era. Checkered black synthetic grips with Colt medallions complete the factory-style presentation.
