![]() ![]() In ascending order of ME generated, the Winchester 127-grain SXT +P+ at 405.5 foot-pounds, Remington 115-grain JHP +P+ at 425.0 foot-pounds, and Federal 9BPLE at 427.7 foot-pounds were another story. They simply don’t offer enough additional ME compared to standard-pressure 9mm to justify their choice over more easily available and cheaper loads. In this regard we’d have to flunk the Federal 124-grain Hydra-Shok +P+ at 357.3 foot-pounds and the Winchester 124-grain SXT +P at 364.9 foot-pounds. Typical standard-pressure 9mm defense-load figures would show a 115-grain jacketed hollowpoint at 1150 fps generating 337.8 foot-pounds of muzzle energy (ME), or a 124-grain JHP at 1100 fps generating 333.2 foot-pounds ME. For ammunition whose entire purpose is to offer more energy than standard-pressure 9mm, we wondered how more velocity these +P and +P+ rounds generated above standard-pressure ammo. The Federal 124-grain Hydra-Shok +P+, Remington 115-grain JHP +P+, and Winchester 127-grain SXT +P+ posted single-digit SDs. Velocity.Every round tested passed the standard for consistent velocity, and several posted tight standard deviations (SDs). What did you expect? This was a 9mm Sig P226. Every round fired passed the reliability portion of the test. The stages are described briefly below a more detailed testing procedure can be viewed and downloaded free of charge at Reliability. If a round was found wanting at any stage, it was removed from the rest of the test, and the survivors continued. Our testing procedure had several stages in it. We acquired it from Bull’s-Eye Shooter Supply (414A Puyallup Ave, Tacoma, WA 98421, 572-6417). Our test gun was an older, though lightly used, example of Sig’s P226 in 9mm, a cartridge/design combination with an excellent reputation and track record for reliability and accuracy. Winchester Ranger brands were the 124-grain SXT +P (No. ![]() From Remington we tested the 115-grain JHP +P+ (No. Also from Federal was the Premium 124-grain Hydra-Shok JHP +P+ (No. Our test ammo included the Federal Classic 115-grain Hi-Shok JHP +P+, product code 9BPLE, basically the company’s famous 9BP load pumped up to +P+ pressures. For instance, while this article was being prepared, we received word a local commercial gun shop had just gotten in a big shipment of Winchester +P and +P+ 9mm. In this article we tested five hot 9mm loads, because, though this ammunition is ostensibly “police-only,” it does tend to find its way onto the commercial market. The exception to this rule is Winchester, which restricts both its +P and +P+ 9mm to police-only sales. 40 magazines holding the same number of rounds, many shooters decided, “If I can only get 10-shot mags, I want them holding the fattest rounds possible.” Now that the ban’s expiration has restored the 9mm’s capacity advantage, we look for the fortunes of this cartridge to recover somewhat in the future.Īs a general rule, 9mm +P ammunition is sold to both police and the general public, but +P+ 9mm is sold only to police agencies, which have to sign a waiver saying they won’t sue if anything goes wrong. Among ordinary citizens, the 9mm’s popularity was adversely affected by the now-expired Assault Weapons Ban and its prohibition on importation or domestic manufacture of detachable box magazines holding more than 10 rounds. Once it was the most popular police cartridge in North America today that title belongs to the. The 9mm’s popularity in police service has taken a hit in the last ten years or so. 357 Magnum 110-grain jacketed hollowpoint, a round most shooters take seriously.) (A hot 9mm generates muzzle energies equivalent to a. A 9mm auto stuffed with +P+ ammo is, in effect, a high-capacity, fast-firing, quick-reloading. Such loads typically increase velocity of a 9mm projectile from between 100 to 200 feet per second (fps). Thus was born the concept of the +P+ 9mm. 357 Magnum revolvers for 9mm auto pistols. By the mid/late-1980s many departments were trading in their. The impetus to develop a higher-pressure - thus higher velocity - domestic 9mm load came from our nation’s police. There’s no SAAMI spec for 9mm +P+ that’s just a way of saying its pressures exceed +P standards. 9mm +P has a SAAMI pressure ceiling of 38,500 psi. standard pressure 9mm and NATO spec, we have two options. By contrast, NATO pressure ceiling is 42,000 psi. The Sporting Arms and Ammunition Manufacturing Institute (SAAMI) has set a pressure ceiling for standard pressure 9mm Para at 35,000 pounds per square inch (psi). The 9mm Parabellum cartridge (commonly called 9mm Luger in the US) has traditionally been loaded more lightly on this side of the Atlantic than in Europe. ![]()
