Chamber the 1911 in 10mm and it can perform. The classic platform was designed for the .45 ACP, made to take about 21,000 psi with 230-grain ball ammunition. In the late 1920s, the gun was juiced up with the .38 Super, which has about 36,000 psi, depending on the load. Introduce the 1911 to the 10mm and you are talking about maximum pressure in the range of 37,500 psi. That’s enough to rattle the old pistol design, but not so with the Rock Island Armory TAC Ultra.
