Nine millimeter pistols like this Smith & Wesson M&P 9c are the most commonly-seen concealed carry guns on the market today. As technology advances and ballistics improve, cartridges fall in and out of favor.
Yes, 9mm is a capable self-defense cartridge. But here’s my question: how many of you do your own testing on your carry ammo rather than relying solely on the numbers provided to you by the manufacturer? If you can do it, testing your own ammo using gel and, yes, the FBI protocol, is a great way to learn more about its performance.
Anyone here already do some of their own testing?
