![]() Speaking of speed and power, let's see how these physical specs translate into ballistic terms. 45 ACP is a wide, slow round that wedges through the air and whatever's standing in its way. The result is such that 9mm is a thin, fast round burning its powder rapidly, while the. And it manages to accomplish while retaining a case capacity that's exactly 50% lesser. 45 ACP are similar in total length, but that's where the similarities end: The ACP cartridge is only 9% longer, yet it produces only 40% less pressure than the 9mm cartridge. And, comparing the percentage difference between these two rounds' diameters (.45 ACP is about 27% wider) it becomes apparent they aren't so similar as any shooter may initially think: 9mm For that reason, it suppresses easily without losing power.Īlthough these two bullets are almost the same diameter by physical measurement, their differences are greater than their similarities. 45 ACP retains a reliably accurate subsonic profile, trading velocity for sheer brute force. 45-chambered Sig Sauer P320s (the P320 chassis can still chamber 9mm with reconfiguration). In fact, some branches have replaced the 9mm-chambered Beretta M9 with. ![]() Army's M1911 handgun, and it remains an in-service round with certain Army and Marine units today. 45 ACP (Automatic Colt Pistol) cartridge is, like the 9mm, a century-plus-old military cartridge designed by the legendary John Browning in 1904. Some loads provide supersonic travel for long-range accuracy, while many more provide reliable subsonic speed and accuracy, making the 9mm perfect for suppressed fired. It has seen service for more than three decades in the Beretta M9 and M9A1 alone, and thanks to its century-long life, the 9mm has been optimized beyond just about any other handgun round. Army, Navy, Air Force, and Marines, and plenty of other NATO and non-NATO forces globally for decades. The 9mm Parabellum or 9mm "Luger" cartridge, as it was originally called by Georg Luger in 1902 (they're one and the same), has been the submachine gun and handgun cartridge of choice for the U.S. But are these the only two arguments to be made? Let's review and lay this to bed. Lovers of 9mm say it's one of the most versatile handgun rounds ever made, and of course, that it provides more capacity to boot. 45 ACP say there are few other rounds capable of providing the same type of "Mac Truck" stopping power. Is there a "better" cartridge overall? Unfired, there's less than one-tenth of an inch of difference (0.095", to be exact) between the two bullets' diameters.
