I installed the Timney on my Savage 210. The trigger was supposed to be a drop in which it was, until I put the action in the stock only to find out the actual trigger was too long to fit into the trigger guard. Fortunately, a few minutes with a grinding bit on a drill is all that was required to remove the unwanted length.
My point being, no matter what they may claim don't surprised if a small amount of adjustment may be required. If it needs more than a little work that would be another story
