I was on the Glock site and they have a package for $11 that has a fixed front sight and about three different rear sights of different heights. The Glock rear sights will not fit the Sigma (obviously) and I was thinking of buying the kit just for the front sight and giving it a shot. I'm not interested in a 'glo in the dark' sight or a fiber optic sight. It's too bad that Sigma doesn't have a package similar to the Glock package.
