I use my 1894 Cowboy rifles in .45 Colt and .357 in CAS competition. That requires open type sights. I have finally gotten the picture and replaced the rear sight with a full buckhorn rear. I also replaced the front with a Bockman serrated ramp front. I now use the full buckhorn as an extended eye relief ghost ring sight. It works very well for me.
My other Marlins, a 336, a couple of �94s in .44 and .357, a 39A and 39A Mountie, all have receiver sights; an old Redfield on the 39A and Williams Foolproof rear sights on everything else. They also have XS systems front illuminated post front sights.
There are lots of ways to get to a good sight setup. This is my preference, but there are other equally good ways to get the same thing.
