How much barrel is too much barrel? In this video we doing 45 velocity test using a chronograph and a 45 caliber pcc. The in the velocity test we use a custom long 45 barrel in the cmmg mkg 45 pistol. 45 pistol caliber carbine s are a usually direct blowback but give the substantial difference required in reciprocating mass in 45 vs 9mm the CMMG 45 uses a radial delayed blowback system to make it more functional across a length of barrels with minimal change in the operating system. Taking the 45 velocity data we came up with a good list of candidates on what the best 45 barrel length in a 45 pistol caliber carbine.
