Ironically, the mags that I'm having the most trouble finding locally are 10 round .22LR mags...
I can find anything for my Glock, and AR/AK mags are plentiful (if not a bit overpriced compared to pre-panic). AR's are now, maybe 10-15% above pre-panic levels, and there's a ton of them available. Ammo, of course, is the issue. I've been trying to buy .22LR ammo for a while and have only managed 4 boxes of CCI Stingers at about $7 per 50 (ouch). I did see some Eley match ammo yesterday, but they wanted $22 for a 50 round box... *sigh*
