I’m all about pinkie extension magazines on compact guns. That little extra purchase can make a huge difference to the shooter’s ability to hit what they’re aiming at. (Always a good thing in the firearm realm.) The standard-issue extended magazine on Ruger’s SR9c gives buyers two guns in one: a good enough concealed carry weapon and an even better home defense handgun. That said, their mag extension doesn’t afford extra ammo. Whereas the newly released SIG SAUER P238 Two Tone with Rosewood Grips gives its owners room for an extra cartridge. The difference between six and seven rounds could be life or death. So you better go out and buy the new model, ’cause you can’t purchase the magazine extension separately. SIG says the longer mags will be available “within a month.”
