Removing front sight from Dragoon or Walker

[JCT]

How would I go about removing the blade sights if needed? Is it fairly easy to remove and put a new one in?
I've been tweaking all my revolvers lately, filing hammer notches, front blades..etc and I'm thinking that the Dragoon is just too off center filed since I got it. A new one may be taller too, which would be a help.

Walker repairing itself

All Walkers shoot way high but when I bought mine (new) it shot about 10cm (4 inches or so) offcenter to the right on 25m (30yards or so).
I had to aim left to correct it.
Now after at least 1000+ rounds through it, maybe even 1500+, it seemes it has corrected itself slowly and at the moment it shoots horizontally almost dead center.

Why I can't explain. Maybe the barrel has set on the frame, the barrel has smoothed out itself, or maybe the fact that the trigger is much smoother now than it was in the beginning.
I use the same BP and balls from the same mold.

Glad that my sight is still on it's original place otherwise I had been aiming offcenter to the right now to correct it.

If you want it to shoot point of aim, remove it with a file and dovetail a new one in place.
