Hi, my Rohm Twinmaster is only running about 2.5ftlbs. It had the assister spring kit, and was still only running a tiny bit over 3, but I took out the assister spring to make the trigger nicer for 10m target shooting.

Is 2.5ftlbs about right as standard?

Also, I have read that adding shims to the regulator will up the power, but it really needs to have the assister spring behind the hammer to work together.
In the same tuning guide, it was saying some minor adjustment can be made by the inner grub srcrew in the regulator, is this worth a play? I had a nose, and the brass cross headed screw in the reg was loose, is it supposed to be locked down against the adjuster grub screw?


Thanks.
