Besides the NRA magazines, Shooting Times and Guns are my two favorites. I check out some of the tactical firearm magazines at the newstand, and occasionally buy. Just don't subscribe. Gun List and Shotgun News are running articles now which are often interesting. Used to subscribe.
I don't particularily agree that most of the gun magazines are not any good. They offer a mix of articles of potential interest to their readers. The subject matter of articles vary from month to month and some months I read just about everything and others I don't read much of anything. That is just the way it is with magazines who try to run articles of wide interest to their readers.
