I have shot a bunch of Jewell triggers, easily 500+ rounds behind them. I have never been in love with them. They are just not for me.
TT Diamonds, I own 4 of them. GREAT triggers. I love them. I run mine at about 6oz.
I also own 4 Timney Calvin Elites. Again, great triggers. I run them at 8oz.
Bix N Andy Tac Sport Pro are the new line I am now buying, 3 and counting. Even better than the TT Diamond in my opinion. Similarly priced, maybe even a touch less expensive. But not cheaper. I run them between 4-5oz.
