I posted that I have it and my glock on FB. I have about 150 friends/family on there, but every friend of mine I know personally and associate with, there's no "fb game" friends or anything... past that, my settings are for friends only so things won't show up in friends of friends feeds or anything.
Past that, who knows what people say when they talk with one another, and i'm guessing some people may even have forgotten already.
Any particular reason you ask, or were you just sparking conversation?
Not many.....wife, grown up son/daug, father,and father in law(both ret. leo), select few others on need to know basis. Most of time, wife isnt sure if I am carrying or not( always do)....I dont really think she wants to know.
