I MIGHT personally have a 28 gun safe with digital access in my bedroom next to alpha bed side. Wife/other/Beta must know how to operate each tool within the safe proficiently and effectively and safely. G17 9mm with JHP on night stand(secured while away) which allows me(or wife) time to access the safe containing a Moss 930 and Moss HD 500 both with 8-10rds+ of military OLIN 00buck in mag tubes. Present 930 first and retreat to find 500 last. Safe should have automatic internal lighting in a frequency not readily seen from a distance (I.E. red or amber, not bright white). ALWAYS "prove" each tool with range time and rds intended to protect. Kids(boys 8 and 10) know that they have to retreat under the the furthest bed (in home) during invasion. Shotguns are a primary tool and the HG is secondary ALWAYS. Learn your transition until they are second nature. IMO 00buck is a force multiplier with 9 -30cal rds per shot(thats 72 30cal rds per magtube minimum). 00buck WILL over penetrate and account for that. These rds MUST be able to be placed on target without question. Spread is minimal in home environmental distances. Practice with all tools is key and spare no expense mastering each. Add 3"+ screws to all door hinges and striker plates to give more seconds to access safe. Always use loud, intimidating tones and vocal commands while commanding an intruder. Let him/her know that death is probable. NEVER, EVER discharge unless fired upon or directly attacked with a deadly weapon. Cell phones on each side of parental beds used to call for police assistance is key to survival/backup in a deadly encounter. IMO of course.
