Hardly a geezer gun. The S&W Mod 27 (from which the Mod 28 was derived) is possibly the finest SA/DA "wheel gun" ever (my opinion, but it's shared), but they are not lightweights, far from it. The Glock family in whichever caliber you choose are simply easier to shoot adequately (also my opinion; any time you get in a conversation about revolvers, Glocks, 1911's it turns to which is best and there is no right answer, they're all good).

My S&W Mod 19 has a 6" barrel with target sights and someone very good at his craft gave it a very light (breathe on it) SA trigger. It's a .357 Mag but I only ever shoot .38 Spl target loads with that revolver. Whatever it has I don't want to mess it up.
