I like Shooting Times, SWAT when they have articles I'm interested in, Guns (sometimes, depends on the articles), Small Arms Review (when an article catches my eye---they are always well done), and the occasional Guns & Ammo and Combat Handguns.
G&A is the only one I ever subscribed to, though (had a subscription for years and it was a big help for me as neophyte in learning my way around guns and gun law, but at some point I realized I had learned most of what they were able to teach me.
