They are a bear to rack the bolt on, he may have figured removing one spring would make it easier.
I don't think it would work right but that isn't the cause of your issue.
I'm not intimate enough with mine to tell for sure what's going on with any certainty.
I'd find a schematic and make sure everything is going together in proper sequence. Also replace that spring.
There is an EZ Pull set up marketed for the Tommy but Kahr doesn't recommend them. I know a few who run them and have no issues though, so juries still out on that one.
