I would say most bolt rifles (Win, Rem, Savage, Browning, CZ, Ruger, ...) CAN be adjusted/worked to #4 without creep.
When you want a trigger at #1.5 that will not slam fire you need to go with an aftermarket trigger
Gonna edit this one... I have a Ruger Semi auto with a good #4 trigger that is safe and a couple of Savage 99 levers with the same
