![]() They asked for ammo that meets their specifications (or as close as the ammo maker could comfortably come), they got it, and any gun breakages, malfunctions or shortened life of service pistols is a problem that falls solely on the agency's shoulders. Once the negotiating is over and the check clears the bank, the ammo maker ships the ammunition to the agency with one clear understanding: The agency is on its own. The manufacturer then decides if they can do it and performs testing to determine what the pressure might be. When it comes to ammunition with this rating, a law enforcement agency typically solicits an ammo manufacturer to engineer a load that propels a selected projectile to a specific velocity range. What is +P+ loaded to? It does not have a defined industry standard. ![]() In the 9mm, the standard maximum is 35,000 pounds per square inch (psi), and +P is 38,500 psi. Ammunition that is +P rated is loaded to a higher, albeit still safe and known level. But then there are the +P+ loads, and those, well … SAAMI provides pressure specifications so that we know our ammo is safe, and pistol manufacturers know what they have to do to deal with the increase in pressure. The first are known as +P loads, and most service pistols of quality can handle them. Some of these loads are approved by SAAMI, while others are restricted but available. Why should we bring SAAMI into this conversation? Simple: You can do all sorts of detrimental things to yourself and your equipment by exceeding standard pressures - if you're not careful. They are from Liberty Ammuntion, Pol圜ase and Super Vel. Now we ask: When is there enough bullet velocity? When is there too much? For some, that is not a question but a challenge.Ĭurrently, there are three high-speed factory loads that can be found in volume on store shelves that stay within SAAMI pressure specs. Bullets were full weight, and they didn't move all that fast, at least by today's standards. What seems like a lifetime ago, I was working in radio broadcasting when I first heard the unofficial motto of rock 'n' roll: "Some is good, more is better, too much is not enough." Back then, handgun bullets were simply made of lead and copper.
