The 4506-1 configuration brings the stainless slide and frame with a matte bead-blast type finish and the rounded trigger guard associated with the -1 update. The 5-inch stainless barrel, short-recoil locked-breech system, and DA/SA operation provide a proven .45 ACP setup with a spurred, checkered external hammer and a one-piece wraparound synthetic grip.
Controls include an ambidextrous slide-mounted safety/decocker with a red index dot, along with a firing-pin safety and a magazine disconnect. The slide is configured with rear serrations only and an external extractor, matching factory features for this model.
Sights consist of an adjustable black rear with a top screw and a fixed front blade that carries a white insert for a clean sight picture. The frame is marked "Mod 4506-1," and the barrel hood is marked "45 AUTO," confirming model and caliber at a glance.
Dimensionally, this full-size pistol measures approximately 8.5 inches in overall length and weighs about 2.6 lb unloaded. It uses a single-column magazine system, and this example ships with four stainless magazines to keep range or duty rotation simple.
