They are not "hard" to install, as such, if you follow the instructions and if you have worked on (i.e. removed) the Ruger triggers before,
BUT, that assumes the the pin at the rear of the action that holds the safety transfer bar and safety spring will come out. This pin must be removed in order for the Kepplinger to be installed. I've tired to remove this pin on several actions and it simply won't move; almost like it was cast in place.
On the #3 custom I finally installed my Kepplinger on, the pin came right out (as it should).
