I just checked my K31 trigger and the initial "first stage" is 1 3/4 pounds and the "second stage" 3 1/2 pounds. As a Marine Corps Armorer, we had to do a lot of honing and part changing to get the required minimum of 4 pounds on the Garand. Of course there is a whale of difference in a semi auto trigger compared to a single shot bolt action. I admire the crisp "let off" of the K31. Not as good as a Jewell, Rifle Basix or a Timney which I put on custom rifles but a grand difference in price. The K31 trigger is the best trigger I have ever found on any military rifle. One of the worst is the M16 trigger, I just replace them with after-market triggers on customers' rifles, rather than spend hours honing and tweaking them.
The K31 has some back lash but most shooters wouldn't notice it unless he knows what to look for. Fine trigger! Just plink away and enjoy the excellent accuracy and soft recoil and remember to take up the slack. I can remove the first stage but it isn't necessary, nor in my case, desirable.
