Any high capacity pistol mags are really in demand, but some dealers aren't jacking prices just to take advantage of the situation.
I shoot STIs and want to give a shout out to Dawson Precision, an STI distributer. On his website prices for hi-cap STI mags haven't changed at all. In fact Dave Dawson has a statement on the site saying he won't raise his prices unless his own mag costs go up. While you might have a bit of a wait due to demand, you can still buy at reasonable prices. It's nice having a shooter running a gun company. He gets it. Thanks Dave.
