Of the 3, two are from my late grandfather which haven't been used by me, and were used for target practice by the retired marine and my father. The other is my supersonic air-soft rifle, which I have blasted poor apples and containers to bits with. No violence occurred through these weapons as no animals were killed and nobody was threatened by them. However, my justification for their presence is that they are single-shot, so I can protect myself yet I couldn't easily shoot many people with it.
