I just worked on an older Glock that had a 6# trigger pull. I highly polished all trigger components, installed a Ghost connector, a 5# Wolff FPS and a new OEM trigger spring and it went to 4#. A Gen 5 G45 with highly polished trigger components, a Ghost connector, 4.5# FPS and a lighter safety spring has a 3# 4 oz. trigger pull. I recently installed a Johnny Glocks trigger in a Gen 5 G45 and it had a 2# 10 oz. trigger. All were 10 pull averages.
