I eased the trigger on my Sigma a little more and the accuracy is coming along.
I had already done a trigger job on it to get it down to about7#. I decided to try the trigger mechanism with just the ball point pen spring. This really lightened the trigger. I had already modified the striker spring making it about 21# over the original 18#. It adds to the pull a little, but there are no misfires at all and the gun handles a lot better yet.
