I wish I could buy weapons on Craigslist.
Out of curiosity, what gun do you have?
GUN haha. At the moment I only have a USP9, Cz82, M39 mosin nagant, henry .22 lever action, an uberti 1873 cattleman, and 2 single shot .22 boys sized rifles from 1907. I've had many many more before that though. Weapons on craigslist would be neat but shady as fuck, a lot of states have a dedicated weapons trading forum and those tend to be pretty good so i'd stick to that.
All I'd look for on CL if we had it would be weird, disturbing sex ads
why not look at ones in the big cities in the us, LA, NY, DC, ect and see if you can find anything that suits your fancy
