The good news is the Kepplinger trigger is very easy to install and it is much better than the Ruger trigger. However it is very slow. I do not like the over center kick off as I think that is why it is not as good as a proper double set trigger.
I have a friend who is working on a self setting trigger that is very good and have had a prototype for about 4 years and it is great but have no idea if or when he will get it in production.
Cheers,
Laurie
