Has anyone in the group changed the sites? The front is held on with a retaining clip that I cannot get off. The rear have a cover over the set screw that holds it in place on the top of the site. The cover looks fixed. From inside the slide the rear has a an allen head hole which I presume means you remove it internally rather than externally.

It is the wife's gun and I really do not want to damage/scratch trying to replace the sites so all help is appreciated.

Thanks!!!
