Eventhough I usually carry 2 guns on me at all times xd45c or 1911 5" on my hip, my ankle gun is usually a J Frame or a Para Carry 3", i keep a shortened Mossberg 500 12 G in my truck for those times when the **** hits the fan and i gotta make a hole to get out. I was actually considering "making" a clip on for it inside the roof console so its easier to access it. At some point I had picked up a Bersa Thunder 9C for cheap and that used to stay inside the console between the seats but that got stolen LONGGGGG time ago.
As of now, either S&W 642 .38 special, or Llama Mini Max .45acp. When around the house riding I will usually ride along with an additional rifle, either a ruger 77/44 or a marlin .22 mag.
