Re: 9mm Ammo
Probably Mas Ayoob writing about the CorBons. Their tagline for that ammo was "turn your 9mm into a 357" if I remember correctly. Peter Pi's outfit used (from what I read) either duplex loadings or special poders to achieve very high velocities with surprisingly low muzzle flash. In addition to smoking fps, accuracy with CorBon ammo was usually among the best in most firearm tests or ammo shootouts.
I carry Speer Gold Dot 124 grain +Ps in my Sig 226 and my stepdad carries the same in his Grock. They are very accurate and perform great in tissue (several coyotes, rockchucks, prairie poodles, and a goat or two would agree if they weren't dirt-napping). According to testing, they also do well on tissue <span style="font-style: italic">after</span> passing through intervening materials like auto glass, heavy clothing, and sheet metal. Very popular with law enforcement agencies nationwide with good reason.
