Well, you might consider that when YOU use the term "gun", I might think you're speaking of the crew-served, fully automaticvariety, or a non-high-angle capable (generally anti-tank) cannon?

Of course, considering the context of our posts here, I think I could be pretty confident that you're speaking of neither, check or hold? (that's military for "am I right or am I wrong").

Consider this - quite possibly, could the person who called you be a college student who as late as last semester was still in Iraq or Afghanistan, wishing they were home to hunt like they did before they joined the military?

Nothing's forcing you to sell it to just anyone, but I don't think a mere phone call and the term "weapon" ought to be enough to disqualify someone. After all, it might be me who made the call - and we don't call them "guns" at my house. Vote your conscience though, it's your weapon to do with whatever you wish.
