My dad had several guns in the house under the bed and 1 in the nightstand. All loaded ready for use and no locks. My dad took the time to take me out and let me fire the guns so that it was not a big mistry as to what it was like and he ALSO took the time to let me know that if I EVER even thought about touching them with out him around I wouldn't sit down for a week... I never had a problem with wanting to PLAY with any of his guns.
Also there is nothing like the sound of a pump shootgun down a dark hallway.
