It sounds like a good set-up to me. I know the glorious S&W .357 Magnum Tactical Revolver uses a brass bead front sight!
AmeriGlo's website has a sight calculator...
You'll need the specifics of both sights, and you'll have to decide which sight picture you want--i.e., spot-on, or six o'clock hold--to proceed.
Be prepared to email or call the OEMs, as very often the specifications of sights are not offered, and when they are, they mix metric with SAE.
I've read posts here of folks using and XS Big Dot front sight along with a Glock OEM rear sight, and loving it!
Good luck! Let us know what you do and how it works!
