Description
The U.S. Rock Island Arsenal M15 General Officer Pistol, “Serial No. GO,” is a rare and exceptional prototype that showcases the meticulous craftsmanship behind developing a unique sidearm for Army generals in the 1970s. Due to a shortage of Colt 1903/1908 pistols, Rock Island Arsenal crafted the M15 using 1911/1911A1 components, resulting in a custom variation of the Colt Combat Commander.
This particular prototype is marked “Serial No. GO,” a significant designation discussed by Army brass. It makes it the template for future production M15s, which are followed by serial numbers like “GO 1” and “GO 2.”
This historic pistol, featured in Edward Scott Meadows’ “U.S. Military Automatic Pistols 1945-2012” (page 121), is identified as a “General Officer prototype with third type slide and serial number markings.” The slide is engraved with “General Officer Model/RIA,” and the pistol features serrated high-rise blade front and square notch rear sights, sharply checkered front and backstraps, and walnut grips.
The grips display a blank inscription panel on the left side and Rock Island’s “crossed cannons” emblem on the right. This pistol, with its unique features and historical significance, is a testament to the craftsmanship of its time.
The Rock Island Arsenal M15’s components include:
- A chrome-plated barrel.
- An unmarked blued magazine.
- A serrated spring plug.
- A spring-loaded recoil spring guide.
The 4 1/4-inch barrel is chambered in .45 ACP, and the pistol retains 98% of its original blue finish with minor handling marks and cycling wear. The grips and firearm mechanics are in excellent condition, making this a remarkable piece of military history. The pristine condition of this pistol adds to its value and historical significance, making it a truly remarkable piece of military history.
This Rock Island Arsenal M15 is a testament to its importance in the lineage of U.S. Army General Officer pistols.
