I have a model 539 I love it. Very reliable, a little on the heavy side but still easy to operate, price wise I lucked out and bought mine from a widow for $100, in ok condition with 1 magazine. Love how it's an all steel pistol definitely beats these plastic glocs they sell these days, the grip to this pistol just feels right, very comfortable to hold. I'd buy it if I were you, believe me you won't be disappointed.
