Subscribe to most any of the major mags for a year, hang onto them, and you'll be covered for several and won't have to renew for several years because they're basically just rehashing the same stuff over and over...along with glowing, never negative reviews. American Rifleman has more articles that I'm interested in over all the others. If you're new to guns G&A and others like it are great...for awhile. After that newness passes, I get bored with articles mainly about the latest and great new products I'm never going to buy. Once in while I may pick up a single issue because of an article, but that's about it and I've found forums to be the best place to get honest reviews of new stuff.
Precision Shooting is the only one I've kept renewing, but it's about long range rifles, that gear and reloading so it wouldn't be of any interest to you.
$50 can probably get you a year sub. to 3-4 mags if you look for their special rates, get 'em read 'em for a year and weed out what you like and don't like. Most of the major mags have special rates that hover in the $10-15 a year rate, which makes giving them a test drive painless.
