Picked up a three inch 38 Special a few years ago. Around $600 as I recall. This batch appears to be four inch 357s. I'd say the price is fair for an uncommon, almost rare revolver.
Solid guns. Basically a Ruger Speed Six with a side plate instead of a solid frame.
To my way of thinking when it comes to Manurhin, it's the MR73 or nothing.
I'm not aware of anything about the MR88s that make them superior to a plain cut Ruger upon which they're based, in which case I'd rather have a Ruger at less cost.
