Many years ago I had one with the same problem. It has a coil mainspring and I cut off 1 coil. If you're not careful you'll make it too light and may have light primer strikes. Go slowly and if need be you can shim it back up or replace the spring.

If you want to play with the springs, you might consider going here:

then if you don't like it, you can always change the springs back...
