There was one for sale during last weekend's gun show and I enquired about it but did not handle it, now I'm curious about it. Since I am in the elderly class most of my experience has been with revolvers so I know very little about the semi-autos. Will someone please give me the details as to this specific Model 4586? Someone did state that is a double action only and I may have a chance to purchase if he hasn't already sold it. Thank you for the information and any recommendations regarding the purchase.
