I was 23, had my first engineering job, and a co-worker was into competitive shooting, and talked to me about it a lot. I went out and bought a Ruger Mark II target pistol with a 5.5" bull barrel, which I still have, at the same LGS I still go to for their indoor range, ammo, etc. This was in 1989. I believe I paid something like $250 to $299 back then.
Right now the Ruger Mark II or a Marlin rifle are what I am most likely to be shooting at the range, until other ammo prices come down. I keep telling myself I am going to buy a Ruger Wrangler, but considering I have yet to finish the lowers for two AR-15's that I am building, probably not a good idea!
