Built by IMBEL in Brazil and imported by Springfield Armory, Inc. of Geneseo, IL, this Government-size 1911 retains the classic 5-inch barrel format. It is finished in a practical two-tone scheme with a matte black slide over a matte olive-green steel frame, pairing durability with a distinctive look. Slide features include rear cocking serrations with a vertical pattern for confident manipulation.
Purposeful custom touches improve control and shootability. The beavertail grip safety, long skeletonized trigger, and commander-style hammer complement the textured synthetic G10-style grip panels. A flat mainspring housing with vertical serrations aids traction, while the front strap remains smooth for a traditional feel.
Sighting is straightforward and robust, with a small blade front sight and a low-profile square-notch rear set in a dovetail. The pistol runs as a single-action, semi-automatic with a single-stack magazine system, and incorporates both a grip safety and a left-side manual thumb safety. Capacity is 8+1 in .45 ACP.
Markings of note include the barrel hood stamped "S.A. .45 AUTO." along with frame and import marks reading "IMBEL MADE IN BRAZIL" and "SPRINGFIELD INC GENESEO IL USA." A WW-prefix serial was observed. One Chip McCormick Power Mag 8-round magazine is included.
