I haven't seen the particular question discussed. The typical 4 (Handgun, riffle, shotgun, 22lr) are usually what people discuss having, but how many? So for me, we are a family of 4. While the kids are not old enough to handle everything yet, would it not be a good idea to have enough for them as they get older? So I'm thinking of 4 of each category and this is being considered for a long term SHTF situation.
