I just augment more ammo for what I am carrying. I run with a Glock 22 most of the time and I keep two extra 33 round mags in the car and a pair of 30 round AR mags. Both spares are loaded with ball ammo, I figure if I get through 15 without solving the problem more penetration might be beneficial. Also it give me a little plinking ammo if I decide to stop someplace.
VI, if you're talking about Scherer 30-rd .40 mags, don't trust them! Treat yourself to a few Glock OEM 22-rd G22 mags. They work great!
