I've got a Browning/Miroku B92 in .44 Magnum with a soldered on one piece front sight. Miroku later moved to a two piece design with a replaceable blade, but mine is an older one that doesn't have that.
The problem is that the factory sights are darn near invisible - useless in the field for my purposes. I replaced the semi-buckhorn rear sight with a Skinner barrel mounted aperture sight, and that took the situation from miserable to merely unacceptable. This setup zeroes OK, but the front sight blade is way too small to focus on. I shot some nice tidy 16 MOA groups with it off a rest at 25y
When I moved the target in to 15 yards, I shot about 4 MOA (which might be the mechanical capability of the rifle?). The fact that the groups shrink so incredibly moving the target in says I'm definitely experiencing a front sight focus (or lack thereof) issue.
On my 1886 I use the same Skinner rear and a Skinner dovetail front sight spray painted orange on the face. That setup works great - I've shot fairly consistent MOAish groups at 100y with it. It's also fast enough combined with the barrel aperture sight that I'd trust it for a dangerous game sight. The Skinner front sight is wider and has a sloped, serrated face that hold paint pretty well.
So the question is, how to I get a sight more like that on my B92? I can see several possibilities -
1) Remove the current sight/base, and solder on a new base that would hold a Skinner front sight, possibly cut down to get the right height with the base. I'm not sure which of the available bases would be good - Marbles maybe?
2) Install a one-piece sight (what one?)
3) Mill off the blade of the current sight, and replace it with a slot in the base. Then fabricate a custom blade and solder or pin it into the base.
Of these approaches, I'd like feedback on which would make sense and why. I'm not sure what's involved in removing the existing sight, for starters. I'm going to be hiring a gunsmith to do the work, but I'd like to have a clear idea of what I want done first.
