I smashed a bug the other day. It was a ginormous cockroach that was in the kitchen. The wife saw it and pulled out everything and cleaned it all. Tomorrow I'm putting the roach in the bathroom.
Unfortunately, The State of New Mexico forbids the holder of a Concealed Carry License carrying a second gun. The law does not forbid gang bangers or other illegals from carrying as many guns as they wish. It only prevents those of us who follow the law carrying a BUG.
Frankly the chance of a civilian using even their main carry is pretty small, I've never seen the need for one. Being an LEO would be a big difference however.
I don't carry a back up gun and can't remember the last time I did. Now when I travel in or through New Orleans, mostly to go visit my mom, I've got a SIG Rattler in a bag in addition to my CCW if you want to call that a back up gun!
