dovetail sight removal/installation???

Wanting remove a rear sight on one of my Marlin guns, and install a receiver peep sight. I have never had the need to remove one, only adjust for sighting purposes. I have read that the sights are removed both ways, and on some sights it doesn't even matter. Seems to me that it should matter since the dovetails should have a taper on them to stay tight. Is there a rule of thumb, or a saying that sticks in your head? Does it matter front or rear sights, pistols or rifles? Guess I could order a 3/8" blank and just measure it, but was just wondering. TIA...

    Thanks. I was thinking "right in", but then I looked at this website, who sells sights, and it appears to be the opposite..

    It's on the update part.

    Are all dovetails the same, or are handguns different?

    Dovetails are cut on a milling machine with a dovetail cutter-hence are the same width all the way across.
    Friction is caused by the vertical cuts, not the sides.

    Some old dovetails were cut with a safe file. They can be tapered slightly. Looking at the sight from the shooting position normal is push it in from the left to right. I have seen them both ways - it pays to be gentle. Then there are ones for like magazine tubes, that are turned in not pushed in from the side.

    High Standard cut the slides with a straight slot but the dovetail on the sight was tapered and the right end was the narrow end. 0825 per foot

    I removed the rear sight on my 1895CB L to R as holding the rifle to fire it. I installed a blank (Weaver I think), R to L. The blank turned out to be too "tall". I had to wrap some good emery cloth around a file and take some metal off the bottom. I didn't expect that. I mounted a Williams 5D sight. I sure wish someone still made blued steel peep sights.

    Those Skinner Sights are something I'd go for If I didn't already have the oversize, Black, shiny, clunky looking 5D on it already. Someone posted something about the Skinners a while back. It says they're adjustable for elevation. With a 45/70, I wonder if it has enough. Thanks FM.
