I don't really like 30 round magazines - they get in my way on the bench and I generally find them heavy, cumbersome and unnecessary. But on Dec. 15 or so I figured maybe I'd better grab a few before some idiotic politician decides what's best for me. Luckily Midway still had Stoners for about $13, because I probably wouldn't have paid much more than that. At the very least maybe they'll make good trading stock someday.
Mostly my response has been adding stock of my most-used reloading components. I learned from the 2008 shortage and try to keep my personal inventory up now.
