Apparently I'm confused on the role played by hammer vs. trigger springs. I thought like on an AR they could be totally independent, meaning you could have any trigger weight you wanted while retaining the same hammer spring weight. JP says it don't work that way though. If you want their 3 pound competition trigger, you have to always use real good handloads because cheap factory loads won't work well. If you want to have good primer strikes with crappier ammo but still have a fairly light trigger, get their 3.5 pound enhanced reliability trigger. If you need 100% reliability on the primer strikes, get a 4 or 4.5# duty trigger. Basically a lighter trigger also means lighter primer strikes. A Geissele SSA-E is apparently the same way. It's 3.5 pounds and comes with a lighter hammer. They just act like it's faster though, don't warn about light primer strikes. Anyway, can you not get a light trigger along with a hammer that strikes the primer as hard as a heavy trigger? I'm guessing that accidental discharges may be an issue with a heavy hammer but light trigger but I don't know exactly.
