I have read the faq's section on sights a couple of times but I came up with an idea and am more confused now than when I started.
I realise that diffrent calibres will sometimes require different barrel diameters, therefore diffrent site bases.
If I don't have to change the rear site base on my Handi 500 s&w, I should be able to put any open site or fiber optic site or peep site on that base if the dove tail is the correct width? No
Just leaving the height of the front site in question.
I'm asking because there are few sites for sale here in Australia or available for international order, but none say what barrel diameter the base will suit, or they can't tell me if the pre drilled holes in my H&R will line up with their site base.
So I'm grasping at straws, take their site off it's dove tail base and put it onto the 3/8th base that is still on my Handi.
Has anyone done this kind of mismatch before?
