Description
Ever hold history in your hands? That’s what it feels like with this Colt Government Model Prototype. Built during a short run in 1970, this pre-Series 70 prototype isn’t just rare—it’s a marker of transition. Colt was experimenting, refining, and pushing forward—and this pistol was right there at the tipping point.
Only around 1,000 of these were made before the official Series 70 line launched. What makes this one stand out? That distinctive “BB” collet-style barrel bushing. The “BB” stands for “Barrel Bushing,” but what it really meant was Colt was stepping into a new era—testing a system that would soon redefine their production standards. Pair it with the flared barrel, and you’ve got a setup that boosts accuracy and reliability well ahead of its time.
Of course, it’s chambered in .45 ACP with a classic 5-inch barrel—nothing flashy, just dependable power housed in a frame that feels as right in your hand as it does in a display case. The rich walnut grips? They’re the kind of detail you don’t see much anymore—warm, textured, and full of character.
And yes, it still has its original matching box and Series 70 manual. That alone adds a layer of story most guns can’t match.
Whether you’re a seasoned Colt collector or someone who appreciates a turning point in firearm history, this prototype is more than just a pistol—it’s a moment frozen in steel.
