Not much difference in the 43x
The factory trigger was very hard maybe 8 lbs. Installed the connector which didn't make much of a difference. Removed the connector and reinstalled it still did not feel very good. Installed it in my 43 and made a huge difference very smooth and much lighter. Installed a double diamond in the 43x, made a better feeling trigger but still not satisfied with it. Hoping it get a little better with use.
