I hope scenar comes back here. I would like to hear his take on the differences of the Primary and Special vs the Diamond besides the weight. I love reading his post.
All 3 use the same sear engagement technology, but there are a few more “working” parts in the Diamonds and believe they are housed differently internally.
All have an external weight adjustment. Primary and Secondary are 1ozs per click of the adjustment screw, while the Diamond is a variable adjustment. Don’t recall the numbers, but as you go up in pull weight on the Diamonds, the value of the adjustment click increases as well.
