Aftermarket support for Springfield Armory pistols is disappointing, to say the least. Though all mine still shoot better than I do, I'd like a threaded barrel for my 'ol XD40 4" service model, a 357SIG or 9mm conversion barrel would be nice too. Only option is like $250 from Bar-Sto. Granted I'd get what I paid for in the barrel, it just isn't worth that much to me to.
