Seems like it'd be possible, but you're would need to remove about 1/2 of the grip frame structure as well as some of the rear part of the body where the sear slides in order to have a microline fitting attach.
Picture of what I was thinking
Any input? Like I said, it seems like it'd be possible/somewhat straightforward to do this.
Just bob the valve/make an ASA to stock adapter to run any stock you wanted and not have to worry about air.
