![]() With so many different case manufacturers, there is a huge difference in their construction. Some ammunition companies list 9mm +P+ loads, which are not regulated by SAAMI and are loaded to proprietary pressure levels and velocities, so are only recommended for select guns. ![]() This brings us to 9mm Luger +P loads that operate at a maximum average pressure of 38,500 psi, and again are not recommended for all pistols. Check with firearms manufacturers to determine if they recommend using these higher pressure loads in a given model. As a result, surplus 9mm NATO ammunition is not recommended for all pistols, particularly vintage guns. Using the correct combination ofĬhanging overall cartridge lengths from suggested listed lengths can change pressure ponents, handloaders can usually exceed these velocities while staying within pressure guidelines.įor clarification, the 9mm NATO often utilizes a 124-grain FMJ RN “Ball” bullet at 1,250 fps, which is loaded to higher pressures than 9mm Luger commercial ammunition and is listed with a maximum average pressure of 36,500 psi (proof loads are 45,700 psi). It is important to understand that these loads are almost always at least six percent to 10 percent below industry maximum average pressures, which leaves a proper margin of safety. manufacturers at around 1,190 fps, 1,150 fps and 990 fps, respectively (velocities do vary slightly from various manufacturers). The three most common bullet weights are 115-, 124- and 147- grains, which are generally listed by U.S. loads suitable for all pistols produced for the U.S. (the European equivalency of SAAMI) lists maximum pressures at 34,084 psi, making virtually all commercial European and U.S. SAAMI maximum average pressure was traditionally established at 33,000 CUP but has now been updated with modern piezoelectric pressure measuring methodology and is currently listed at 35,000 psi. 749 inch.This feature is specific to 9mm Luger “standard pressure” handloads, which needs some clarification before proceeding. Expanding bullet technology has played a huge role in making the 9mm a viable defensive round, which in addition to being offered in factory loads, are readily available as handloading components. Today the selection of premium defense and law enforcement factory loads (including +P options) is nearly endless and includes expanding monolithic bullets as light as 95 grains at over 1,500 fps, various 115- to 124-grain expanding bullets at velocities around 1,400 and 1,300 fps, respectively, and subsonic loads that usually contain 147-grain bullets at around 1,000 fps. ![]() These loads helped put the 9mm on its way to becoming a viable defense and law enforcement cartridge, but that was just the beginning. Winchester followed in 1979 with its 115-grain Silvertip bullet at 1,255 fps. produced examples included Colt’s Model 1911 Commander and Smith & Wesson’s Model 39, as well as war time souvenirs such as the Luger P-08, Walther P-38, FN, Browning and Inglis Hi-Power.ĭuring the 1960s, Super Vel Ammunition (as operated by Lee Jurras) pioneered a 90-grain JHP load at around 1,400 fps.
