The earlier 1st “10 most manly guns”
I highly recommend #9, the mighty M44 carbine from Russia!

It's a comfortable revolver, and if .44 Magnum is too much, you can load it with .44 Special instead. It is stronger than it needs to be, quite accurate, and instantly recognizeable. Carrying it in a well-made leather holster says that you are, in fact, a man and you take no crap.
Mine is the Model 629 with special NRA engraving. I'm still looking for just the right leather rig for it. I know, I'm discriminating, that way.
