I would think that's going to be a pretty small market just like the Sig P320 grip modules. There is already some flexibility in the Gen 5 since the same locking block is shared by full size, compact, and X. Lone Wolf makes dust cover adaptors, too.A personal weapon set up with a common recoil spring and locking block would have the ability to use either length slide. Not a huge selling point but one some people would take advantage of.
