Looks good! Love that freedom of manufacturing

Not a bad idea, however the tolerances stack up of the p320 FCU holes is pretty critical to the function of the pistol. The spacing of the pins is critical to proper sear engagement, its the mechanism that the take down safety and the manual safety uses. No sure how confident I would with in a bootlegged rig. Of the three I have, one had some funny business when I dropped a gray guns trigger that slightly messed with the linkage distances.

Given how easy it is to move stuff around on P320s I really like the look of this. More 80% pistols are a very good thing.
