Combat Handguns, American Handgunner, and good ol' Guns & Ammo help me kill downtime. It's also fun to look thru an occasional Shotgun News and see what prices are like.
Guns & Weapons for Law Enforcement is pretty cool-some of the toys in there seem like they could be mainstream someday. I love the combat shotgun reviews, but the $2,000 .308-of-the-month club thing is getting stale. I didn't even know there were that many AR-style .308's in production. Just my opinion, that's why there's something for everybody.
Also like the Legislative Updates in the NRA magazines.
