4 of 5 Issues, but I was able to fix them. October 23, 2021
Reviewer: Honest John from Milwaukee  
Purchased for my two year old GSG 1911 .22LR BUT either it or my gun are machined wrong. It simply will not fit on the right side. Either my gun's groove is too narrow or the mainspring housing "ridge"  are too big. Bummer. I am unable to find another gun like my to compare, I have no idea what to do here. My local gunsmith says the two parts will never fit together unless one is machined. Not what I was looking for.

UPDATE!!!     (Oct 23, 2021)
After milling away .085" of width from the "ridge" on one side of the housing, it now fits perfectly. I am pleased with this outcome, all works well and the gun feels great in hand. Shoots well and looks great.
I still can't give it 5 stars since I received NO help from the seller and I was responsible for fixing the miss-machined part. Mag well looks OK and helps with my very large hands. Reloads are a snap now.
