I very much appreciate the valuable input from those who have been there and done that with these grand single shot rifles with 28" round bbl or 34" heavy octagon, along with rear mounted tang sights. My reason for asking the questions was to see what those experienced in shooting these rifles were doing. I think we have had some valuable input. As stated in the OP I knew there was no pat answer to the question and ultimately it must be decided by the one doing the ordering. I have very little real world experience on this type of single shot rifle and desire to not make a mistake in ordering the various options available if given good input from those in the know. I have made several decisions on the purchase and have taken the input here as a guide. Just so you you know, the rifle will be configured in the following ways: C. Sharps, 1874 Bridgeport Sporting Rifle, 45-70, 30" Heavy octagon bbl, semi-fancy stock, pistol-grip stock with steel checkered butt-plate, cheek rest with accent line, Schnabel type forearm, double set trigger, deluxe mid-range tang sight, buck-horn rear barrel sight, globe with .025" post front sight. That is what I have decided would be a good 70th birthday present for me. It should be here along about the first part of January. This has been a bucket list item for a couple of years and if I don't do it soon I won't get to enjoy it. Many thanks to all for your input in this process.
