I just bought a brand new gen 3 G21 and I bring it home Saturday. I've been curious about this for a while: when can I defend myself? I'm not going to have a ccw nor can I open carry. I have an example situation. Say I'm on my way from my house to the range. (I ride a motorcycle) I have my handgun in an appropriate bag legally separated (gun separate from magazines etc.) if the need arises can I use it then?
