M_C_Woodsman - I agree with you, but I offer another option: AR-15 with a 22lr kit. Now, granted I have not had any personal experience with them, but, the idea of a drop in .22lr kit seems to have a lot of merit. Drop in the kit and now you have a good squirrel and rabbit getter to put food in the pot. Conversley, when the need arises, swap the .22lr kit for the regular bolt, and if you had been stockpiling good JSP/JHP ammo, you have a rifle that can take deer-sized game and also to defend yourself with.
Whereas for a social disturbance type event, a PCC in 9, 40, 10mm or 45 is excellent choice as well. Most of the shooting that will need to be done will be done at SMG distances, eg completely within 100 yards, and more likely then not inside 25 yards. A fast, light, low recoiling shoulder arm makes a lot of sense. A sub2000 weighs what 4lb, and can feed from a glock 33 round stick magazine. So there you have a small light carbine that you can quickly and accurately put down 33 rounds of good JHP ammo at whatever 2-legged threat comes your way.
