I like the kind of firearm related shirts that look innocuous to most people but that makes other gun owners nod your direction when you pass them in the store. The new Glock Sight Picture from Russian Roulette Clothing is one of those shirts.
To your gun buddies it is one of the most recognizable sight pictures in the world of firearms (even though everyone with sense replaces those nasty plastic things Glock calls sights as soon as they get their new Glock home). To the guy who makes your coffee it is some kind of modern art logo or something.
