hittman,
I would have to give the 4" Police Sevice Six (with factory wood grips) a ton of credit too. Overall, I think that the GP's are probably a better gun. However, I like the feel of the Service series of revolvers better than the GP series.
They just may be the perfect gun, to have on your hip, while thrashing around in the woods. They are somewhat light weight, their current market price is reasonable, they clear leather quickly, no rear sight sticking up to get bumped off, sturdy construction and they are good shooters. I'll never sell mine.
