About a 1 1/2 yrs ago I bought an OM Trooper . It's built on the same frame as Python , same action . It doesn't have the ribbed vented barrel nor high lustrous finish . But I paid $475 and it was in excellent condition , original finish . That is probably as close to a Python as I will ever get . Single action is great , yes it does stack in double action . It just requires practice to get used to it . I have NO intention of ever selling it . Regards Paul
