I know a lot of people will not want to post in this topic, so I am OK with that. (Some people do not want to let anyone know what type(s) of firearms they have.)
I have several layers in my security system (Dogs, alarm system, safes, light sleeper and almost always at home).
I believe my oldest "modern" firearm is my 1964 Winchester 30-30, model 1894. One of my shotguns may have been made in 1948, but tracking the serial number is hard.
The most expensive pistol I own is a Ruger Vaquero, .45 Colt.
I know the guys who are shooting the AR platform spend more on their rifles than I do, but for what I shoot, these guns are not that handy. (Also, 24 years of military service and having to clean that gun has just put me off to it.) I have shot the AR platform twice since I retired in October of 2004.
