I picked up a Ruger GP 100 at a gun show. It has a B-Square scope mount and a Tasco red dot. The whole rig is used but in pretty good shape. I'd like to have the option of using the gun without the scope from time to time. The entire front sight and assembly as well as the entire rear sight and part that holds the rear sight are missing; removed to accommodate the scope mount. What's the best route to a) finding out exactly what parts I needs, and B) where to get the parts. I took a look at the exploded view at Brownell's and am still not sure which parts I need. It also appears that some of the parts can't be purchased, if I'm reading the diagram correctly.
Thanks
