i recently got a good deal from my gun shop, i traded my charters for rugers. i have a sp101 3 inch stainless, and a gp100 4 inch blue, my question is which should i carry and which to keep at home? i will be carrying on farm, hikes, and carrying open here in kentucky, the other gun will stay at home in case someone there needs it. i would also like to know which ammo would be best for 4 legged, and two legged varmints? thanks for any help.
