Ruger | Blackhawk Flattop | 45 ACP | 45 Colt | Blue

The Flattop's party trick is real: two interchangeable cylinders let you shoot both .45 ACP and .45 Colt from the same revolver with no tools required to swap between them. A cold‑hammer‑forged barrel delivers genuine target‑grade accuracy, a transfer‑bar mechanism plus loading‑gate interlock keep it safe to carry fully loaded, and a smooth, consistent trigger around 4.5 pounds makes it a pleasure to actually shoot, not just look at. Classic Ruger single‑action toughness with a level of caliber flexibility most single‑actions don't offer.
