They're inertia, and are made exactly like the originals, as far as I can tell. My original is at Philip's, with the left sear being recut, to become my spare. I wasn't trying to upgrade. I really don't think that is possible. I was just wanting a new trigger that had never been messed with to be my everyday trigger. I am extremely pleased with what I got.
Take a look at Don's website. I included a link on an earlier post. There are pics of the different models available.
All my best, SRH
