Here is a picture of my 1895 .405 TD with a Williams receiver sight. This has worked well for me in the taking of many head of big game from Pronghorn to Cape Buffalo:
A friend from Down Under has this scope sight setup on his 1895 .405 and he has had great success with it. I have fired his rifle on a range and the scope works well.
Best of luck with your 1895- shoot it and enjoy it.
