Marlin makes a couple of semi-auto rimfires, a clip, a tube magazine, etc but I believe the action is the same. I think the trigger pull is way too heavy- probably a liability issue. In any event, it is possible to have the trigger pull lightened up a bit, it doesn't have to be 2 1/2 lbs, etc, just lighter. Right now it feels like ten lbs- a 5 lb pull would be an improvement.
