Frog: I know what you mean about things not fitting any more. I can't use many things that fitted me when I was 13 either. The easiest way to deal with a too short stock is just to add a recoil paid, either the slip on kind or a permanently installed one.
As for action jobs, go to the lever action forum and look at the post entitled "Action Job For LSI Puma 45 LC. A number of lever action specialists are listed there. I haven't personallyl used any of them but Coyote Cap was recommended to me by another poster on this site and he was very pleased. I talked to Coyote Cap on the phone and am going to have him to a trigger job on my lever action M-94.
