As a new member who is contemplating buying a firearm for home defense purposes only I would like to ask the forum for some advice.I live in New Jersey and am waiting for the proper documentation necessary to purchase either a handgun or a rifle or both.What I would appreciate knowing is what this forum would advise as a suitable weapon for the purpose of home defense only.My wife and I are 75 years old and concerned about the possibility of " home invasion".While serving as an MP in the US army during the 1950's I carried a 45 Caliber Colt model 1911A1.
