You want to catch a roving eye and immediately impart the concept "I am about guns, mostly." Unfortunately, this rules out a good deal of cleverness. Including, IMO, The Firing Line.
On the idea of "grabbing" people:
Guns For Everybody
-This would be best served by lots of cover images of people who aren't normally on gunmag covers. (Calling Dr. Volk...)
Guns For Fighting
-Fits nicely with SWAT's existing cover style. Also no JBT connotation.
Of course, both of these place a heavy emphasis on guns. More so than the current title.
