Seriously, with the money that you pay for these mags, the manufacturers don't even have the decency to mark the mags with calibers? I don't know about you guys, but the freakin' 10mm/.38 Super/9mm mags all look alike and without caliber markings how the hell are you suppose to tell the differences? I keep having to remark mine all the time because even the permanent markers' ink would rub off. Wanna kill these ads? We can help!
