If you have minimal resources for home security I would suggest a 4 inch S&W 686 as your ladies can use it as well as you. Like it or not some ladies and even some men or elderly can not operate a slide on a semi auto. A wheel gun is a very basic good handgun for the home for self defense IMO and experience. With a CHL (permit) this can be carried when out and about easily with a IWB thumbreak holster as well.
Were I issuing guns to evey home in America I would issue the following as a basic set of personal defense / security and foraging tools.
Pump Shotgun
Scoped Bolt Action Rifle in .308 or 30-06
2 x 38/357 revolvers
A Scoped small bolt action or 10-22 style semi auto .22 rimfire for small game and knee capping rioters or looters.
just my opinion of course.......:o)
You still active duty ?
For at least two more years. I want to finish my degree and get into the "Troops to Teachers" program.
I like your list. At some point I'll get a big revolver.
Since you're AD, you qualify for the Glock law enforcement discount. I'm not a strong Glock advocate, but they are utterly reliable and can take a beating like an AK-47. You can get one for about a hundred cheaper than the MP. But you need to deal with a dealer who can offer than discount.
