EMF's 1873 Great Western II "Californian" is manufactured by F.LLI PIETTA in Italy. These guns feature hammer forged steel barrels and frames that are drop forged and then CNC machined. Additionally, they have wider rear and larger front sights for faster sight acquisition. Just like the original Colts, these "period correct" revolvers have a floating firing pin in the hammer and casehardened frames. This combination of traditional aesthetics with the best modern technology makes the Great Western II the most sought after, durable and reliable single action revolver on the market. - CALIBER .357 REM MAG/.38 SPL - SIGHTS Front Blade Fixed, Rear Top Strap Notched - GRIPS Walnut
