Hornady’s Critical Defense (left) and Critical Duty (right) are both good defense loads. Both of these loads generate between 300 and 400 ft.-lbs. There are two available 9mm options available: a 147-grain load with a muzzle velocity of 1,000 fps and a 124-grain +P load with a velocity of 1,200 fps. I’ve found that this ammunition is not only smooth-cycling and reliable but also quite accurate, producing tight groups in a number of pistol tests over the years. The bullets are loaded into a nickel-plated cases and premium primers and propellants ensure that Defender ammo will function under the worst conditions. Winchester’s proprietary bonding process ensures that the jacket and core stay together, and that guarantees that the bullet will continue to expand and penetrate even through heavy clothing. The Defender is the epitome of modern defense bullet design, a hollow point with a bonded copper jacket, led core, and skiving in the copper jacket to initiate expansion. In 2018, Winchester’s Defender won an FBI contract because it performed extremely well in a variety of bare gel and barrier tests. It uses a bonding process that secures the jacket to the lead core, and this results in consistent 1.5X diameter expansion-even through barriers. Winchester’s Defender is one of the best-performing rounds in FBI protocol testing. They’re presented in no particular order. There's a lot of great 9mm ammo out there, but we’ve chosen seven of the very best loads for when the stakes are highest. But it won’t do that consistently unless you load the right ammunition into the magazine. With the right bullet, a 9mm will do just about anything that can be asked of a sidearm, and that includes stopping a dangerous attacker quickly and efficiently. America’s most popular self-defense caliber-the 9mm-has benefited greatly from this new technology, and modern personal protection allows the 9mm to perform just as well as the larger. This prompted a revolution in defensive bullet design.Īs a result, today’s defensive bullets are far better than the stuff from just a few years ago. Ammo companies wanted FBI contracts and could no longer hide poor-performing “defense” bullets when the FBI test results emerged. Following poor bullet performance, the FBI developed a standard testing protocol to evaluate how well bullets performed. FBI protocol is the primary reason for this. Choose the wrong bullet, though, and either of these guns could fail to neutralize a threat.ĭefensive bullets have gone through a seismic shift in design and quality over the years. ![]() In truth, either the Glock or the 1911 will work to stop an attacker if you hit them in the right place with the right defensive bullet. Argue the merits of Critical Defense ammo versus Gold Dot and you’ll get more of a to-each-his-own response. Tell someone online that his Glock isn’t as good as your 1911 and a tantrum with cursing and name-calling is certain to follow. Oddly, defensive bullets don’t receive that same level of loyalty and respect. 45 ACP? Tempers flare when shooters feel their chosen gun is being digitally disrespected. How many times have you seen arguments about the 9mm vs the. ![]() Oftentimes these arguments spill over onto social media. Speak ill of their favorite firearms brand, favorite caliber, even their favorite holster and you’re likely to hear about it.
