First 'real' gun: Mossberg 500 pump that I bought from Kmart in 1975 with money I saved doing odd jobs & such (I was 14).
First rifle: .22 Remington Nylon 66 that my dad bought me for deer hunting.....got it for Christmas in 1975 because he didn't know I couldn't legally hunt deer with it (hence why I was allowed to buy the Mossberg).
First centerfire rifle: Winchester 94 in 30/30.....a Christmas present from my folks in 1976.
First handgun: Colt Trooper Mk III, 6" barrel, blued, in .357 magnum. Bought it for myself for my 21st Birthday!
....and yes, I still have all of them.
