Glock 22 Gen4 Stock trigger pull was a consistent 6.5 lbs. Removed stock (.) connector, added OEM Glock (-) connector [4.5 lb]. Removed stock Gen4 trigger bar, added OEM Glock Gen3 (nub-less) trigger bar. All parts were polished before assembly with nano oil drop in the correct place between connector and trigger bar. Now trigger pull is a consistent 5.5 lbs and smoother than before. I was hoping for something a little lower with a target trigger pull around 4.5 lbs. What would be the next steps? Heavier 6 lb trigger spring? and with what spring weight (if necessary) using reduced firing pin safety and striker springs? I realize the potential of light primer strikes that come with these changes. Note: Please set aside any "why" preferences in regards to legal aspects, issues or what's right for you, this G22 is not my EDC or CCW therefore just interested in finding the correct parts to achieve the desired trigger pull right now, with the option to increase trigger pull upward if necessary to maintain desired trigger pull as needed should the internal parts wear with use over a period of time.
