Very nicely built 2300S you got there.Enjoyed hearing what your experiences are with it.
Very nice I have the custom shop peace with the 10-in loather walther barrel. Do you have any chronograph data by chance? Also I made a moderator. With a 8-in piece of carbon fiber tube. One hair curler. And cardboard discs. I permanently attached it to the barrel with hot glue. The end caps were made with a taig lathe out of 6061 aluminum. It works fabulous.
