CMMG’s MkG Guard is an AR-15 rifle that is chambered in .45 ACP and feeds from factory Glock magazines. At the heart of the Guard is the patent pending Radial Delayed Blowback operating system that works to harness the strong recoil impulse of .45 ACP. After extensive durability testing, CMMG is proud to announce that the Guard is safely rated for 450 SMC.

The .38 Super is dimensionally identical to the .38 ACP of 1900. The .38 ACP fired a 130-grain bullet at 1,100 fps. The .38 Super was a sensation, noted for its high velocity of 1300 fps and nine fast shots.

At the time, you had to know not to fire a .38 Super in older Colt 1903 pistols.

However, 10mm is a small portion of the Ammo market, so DoubleTap did the right thing and now offers a full catalog of ammunition ranging from rimfire to African Dangerous Game loads.
