I have a 6" 28-2 (1974)....It's a bunch of fun to shoot and is a beast. Ruger; nice gun, built like a brick **** house but, only a fair investment. 28-2; a great gun, also well built and should appreciate faster as an investment. But mostly, and as astutely stated by beagleye....wayyyyy cooler!
FYI, I was under $500 out-the-door with original box and a couple boxes of ammo. I think it is an even-up trade if your Ruger is in the 500 buck range. Do it and don't look back!
