After many years of not owning a revolver I am thinking of getting S&W 66. I found almost new older one with firing pin on the hammer, cylinder recessed for rims, very tight in excellent condition. I also looked at new with floating firing pin and new type barrel. Money a side which one should I get? I am planing on to shoot a lot of light loads in 38 special range with occasional full loads and like the size and balance better than 686. Or should I go for more durable 686?
