Ive taken a very different approach, the key is the arch.
The grip disconnects completely and folds in front of the trigger. The trigger is oem and doesnt fold/move.
The advantage is that the arch holds the grip by the rear and the trigger guards hold the grip in the front. The grip is “suspended” with constant traction from both sides. Works as a shock absorber since the grip is free floating.
Fins on grips prevent side to side play
Im up to 350 rounds and going strong on my current model. Some feeding issues im ironing out
