First, what would be your concealed carry weapon to take with you wherever and whenever.
It depends on the situation and the clothing worn. On a hot summer day when bathing suit is it, I might carry a compact .380 auto suc as the colt Mustang or slightly larger PPK/S.
At other times it might be a firearm such as a short CZ-75 clone or a S&W 6906 or a .45 ACP model 1911 variant. Certainly the Kimber CDP compact model is an exzellent choice. More important than caliber or model is the ability to hit your target. The .38 cal revolver certainly has much in its favor and one is almost always in the pocket of a winter jacket. Mrs. Harpseal is more comfortable with a revolver and her choice is a 4inch barreled Taurus .357 magnum, and/or a .38cal snub nosed revolver. For concealed carry there are as many choices as there are individuals and personal comfort and competence should be paramount.
Second, what weapons (plural - weaponS) would you want for well rounded home defense? Please define what type of home the weapons you list would be best suited for. (apartment, city home, 5-10 acre country lot, wide open spaces)For a small town on the CT shore I favor a large capacity 5.56X45 mm rifle along with a Mossberg 590 12 gauge shotgun. I also heartily endorse the scout rifle as designed by Jeff Cooper. Away from shore aboard a boat I like the above three combined with a good .50 cal Rifle. My personal favorite is the Barret but there are other exellent rifles out there.
Once more we have the issues of choice and personal fit along with budget. Some people are best served by a .30 cal M1 carbine some are better served by a traditional M1. It is possible to get an M1A1 in a scout configuration.
For me, my answers would be thus: For concealed carry, I'm getting a Kimber Compact CDP .45ACP 1911 style pistol. I have one gun right now, but I purchased it a few months back as a compromise between critter protection and home defense. (large frame .357) As such, it doesn't lend itself well to concealed carry, although it can be done. For home defense, I'm in the 5-10 acre country parcel range. I'd like a handgun for close-up protection. I'd also like an assult rifle such as an AR15 with high capacity clips for outside work. Also for outside work, I'd like to have a high capacity short barrel shotgun for sweeping the driveway if need be, along with a good hunting rifle with a well dialed in scope in case I'd need to snipe someone or something on my property.
Of course, I can't imagine any one situation in which I'd need all of these weapons at my disposal. But I can imagine various situation where one of these weapons would be good to perform it's own specialized task.
I know we all like to post pictures of tanks, AAA batteries, and Australian made guns that can fire one million rounds per second. But let's try to stay within the budget of the average American citizen.
You sound like you have what works best for you.
