I want to serrate the back of this slide and the extractor clocks way to much. So Micro welder to the rescue. This new micro welder is really cool. Measure, build up, and cut. No more clocking. The extractor that came with the gun and a Wilson were both the same needing about .030” of weld build up. It’s not pretty but it fixes the problem. And the micro welding will get better with more practice. I want to thank the gunsmiths that post work in progress it has inspired me to do work myself and I have learned a lot. Oh and spent a lot of dough.
