Give me my 870 with various loads, my 1911 for personal preservation and future .357 for back-up...not much need for a long gun when a sabot can reach to 175 yards out of a 12 ga...to each his own, I'm sure others will differ. Not much dangerous game in New England other than the occasional politician...
