Wanted to like it - Anarchy Outdoors Glock 20 Magwell

Let me say that I was looking forward to a budget priced magwell. Boy, I was very disappointed in the fit. If you have a gen 4 G20/21/40 frame, do not order this because it does not fit without lots of work which may include adhesive to keep it on the frame and lots of grinding of your frame to get it aligned with the handle screw hole. They need to go back to the drawing board and recall all those they produced. I like the look after I spent hours getting it to fit. Did I say the fitment is terrible? Also, had to grind down the inside of the magwell so my magazine extension would fit.
