I was just wondering about this, I was reading up about the USP on wikipedia and I saw this.
As the USP was developed at the same time as the SOCOM MK23, the pistol underwent much of the same rigorous testing. The barrel is cold-forged from chromium steel for increased life. The USP barrels are a polygonal profile to further increase muzzle velocity and barrel life. During testing, a bullet was deliberately lodged in a USP barrel. Another cartridge was then fired into the obstructing bullet. The second bullet cleared the barrel, resulting in a barely noticeable bulge. The pistol was then fired for accuracy and the resulting group measured less than 4 inches at 25 meters.
what is the advantage of chromium steel to other steel and what makes it different?
