I'm building a Frankenstein SIG based on a P320 X Compact. I'm looking for a couple items to complete that I can't seem to find. I need a post-recall FCU (9/357/40) and a recoil spring assembly for a subcompact.
If anyone has either of these, please let me know. I can, in theory, pull an FCU out of another one of my SIGs (I'm a SIG fan) but then that one won't have an FCU.
