I keep a cheap Rossi .357 mag with some very hot rounds in my truck locked up at all times. I keep it in the vault in an Uncle Mikes holster. When I drive, I pull it out and tuck it into passenger seat gap:
I keep the vault open when I am in the vehicle so I can quickly put it up when needed (traffic stop). This way it is easily accessible and not visible to those peeking in when I am not in the truck. .357 is a crude beast that can take down with 1 shot, but isn't real fun to shot like my other gun...
I also have a Glock 19 with a Crimson Trace I like to have for snakes when fishin' and general home defense. With the Bullydog extra mag holster - it wont fit easily as it is too big:
But it will fit in the uncle mikes:
Here is a victim I hit under a rock about 7 yards away. Red dot on target and squeeze...
Had the kids put down the video games and poke it with a stick as all kids should. For my CCW - my RCP .380 (with the crimson trace) can stay in my shorts pocket all the time..
