Once this is figured out it will be revolution in the world of homemade guns. Designs will quickly replace all ruger parts with Glock gen3 alternatives by modifying the flat slightly to fit the geometry. I'm following and waiting for this to be solved with excitement.
Did you bend the top one (I'm judging by the straight rails), if so what are the issues with it ? I was under impression that that rails need to be bent last and it should be the easiest part (maybe I'm wrong).
The whole point of this is to design a hand bendable solution. Sure we can bend it perfectly with press and what not but that will filter out 95% of the people. To be honest the bends you have look pretty good (just from the picture), remember the RXM frame will also provide some support and alignment for parts which are not perfect, as long as the rails are leveled, slide slides and locking block + trigger housing fits in this should be golden.
