Their is a limited amount of choices for tritium sights for the ruger p89. These sights are as advertised. They do require skills with a drill punches and files to custom craft the sights to fit. The sights are bright all the time.
I wish their was an option with a differnt color on the front sight.
Pros: Strait forward tritium sights. Always remain lit.
Cons: Require craftmanship to install.
