Last week, I noticed my front sight was no longer sitting flush with the slide. When I went to tighten it back on, the tiny screw sheared off rendering the sight useless. I immediately emailed AmeriGlo, and had my reply the next morning. They said to send it in a padded envelope along with the attached email. In the mail my front sight went, AmeriGlo had it by friday. UPS showed up with my new front sight tuesday. Thanks to AmeriGlo, for taken care of business. Grade A customer service. I think all my guns will wear AmeriGlo in the future.
