I think there is a true lack of "duty-grade" bolt gun triggers that don't suck, and don't feel awful...especially 2-stage.
I know Jewell's aren't 2-stage and are the hair-trigger standard, but I've seen a couple shut down from being dirty and they weren't drop-safe.
Tried the Tubb T7T...not really what I was looking for...skinny trigger shoe, overly light first-stage. The trigger and I just didn't work well together; not really suited for tactical shooting despite being a little tougher to seize up than the competition (per Tubb).
Huber's are highly regarded but they are more of a "set" trigger. If you take up the first stage and let off, you need to re-cock the action or it's not going to feel right when you pull the trigger again. That's a no-go for me. Nice triggers, but not what I'm looking for
Timney's are ok. I see a lot of loose trigger (side-to-side) play on the triggers that I don't care much for.
I've wanted to try the Xtreme 22 CG Jackson's as I was under the impression that they were in the Mk13 (or were at one time?). Advertised as drop safe and the maker of the adapted AI Match trigger assembly...this was going to be my other consideration if the Geissele didn't work.
Cadex would be my 3rd consideration; I like the idea of the adjustable shoe and the geometry. No idea what the internals/inherent safety are like. Kinda pricey for said mapley goodness.
I see a lot of people on the hide are all about TriggerTech and Bix & Andy triggers, but I have never tried 'em. Only the later has a 2-stage.
