Denster, I like your suggestion!
That way the front sight could be replaced or adjusted.
I also like Model-P's suggestion of filing the hammer, so that the front pin would not be too high. I think that Densters suggestion would end up with more of a blade sight.
Is the hammer hardened and therefore hard to file down?
Denster, are you some math wizard to be able to figure out exactly how much to elevate with the formula I gave??
What is the formula you are using?
