I posted time ago about Tumblr where users can post multimedia and other content to a short-form blog . But recently I have discovered more tumblr pages with a lot of new pictures of girls with guns:
More great galleries:
http://sexygungirls.tumblr.com/ (More than 100 pages)http://bitchsandbullets.tumblr.com
http://fuckgirlswithguns.tumblr.com/ (screenshots from movies)
Of course, the pictures can be listed in several of these galeries, and some of them aren't new to us.
Check here the updated list of tumblr pages with girls with guns.
