This was a suggestion I read on another forum with the 43. I'm sure the heavy trigger is just confirming that I need to work on trigger control and I'm jerking it a little bit. I'll get the connector updated then re-assess. The armorer I spoke to said it reduces trigger pull by about a pound. Some of the posts on the forum suggested that the new connector made trigger pull much smoother in addition to being noticeably lighter.Try putting a little more finger on the trigger if that makes sense. On my 43 & 42 I have to place the trigger almost to the first knuckle crease on my trigger finger. On rest of my normal sized Glocks its just the pad of trigger finger. I found that "too little" trigger finger on the trigger was pushing my shots low and left. The shorter distance to the trigger on those smaller Glocks to me equals having to put more finger on the trigger. I Put more of my finger onto the trigger and boom. All was fixed. I shoot my 42&43 almost like a revolver trigger and that seemed to help me. Hope that makes sense and may be worth a try.
If that doesn't get me connecting with my point of aim, I'll try changing where my finger contacts the trigger...want to change one variable at a time. I'd really prefer if all my triggers were the same so that I don't have to consciously think about how to pull the trigger.
