Dad bought me a Ruger Mk 2 when I was 17... though I guess it didn't become officially "mine" until i turned 21. Still have it, still shoot it.
First handgun...
I think its the Sig P226 stamped slide in 9mm. Still have it, and it still shoots great.
Same gun and timeframe as yours Jeff, 'cept I was in my 20's.What was your first handgun?
