I've been googling for the past 30minutes trying to find a machine shop offering different barrels-specifically a 16x1 LH threads, has anyone successfully found a shop that offers this service?
EFK makes a number of FNP45 barrels: FNP & Five Seven Pistol Barrels As for your desired thread and pitch..<strike>not sure</strike>. Just checked: 16 x 1 LH is an option...!
Very welcome! Hope it helps... If you do decide to buy please post back and let us know what you think of both the transaction and the barrel! I've had my eye on one but haven't pulled the trigger just yet... Best; PLong
