I am building a 9x19 suppressor platform on a CCF Raceframes stainless steel frame. CCF strongly recommends (demands) that one use factory barrels for reasons that are beyond the scope of this thread. As such, I am looking for a factory M34 or M17L barrel that is threaded 1/2-inch x 28 tpi as the suppressor is going to be a SWR Trident-9. Why the CCF Raceframe instead of the usual Glock polymer frame? The extra weight of the stainless frame will help to offset the muzzle-heavy feel of the gun with the suppressor hanging off the end of the barrel. I also prefer the trigger feel and grip angle of the CCF Raceframe to the Glock as I am a 1911 shooter. Any ideas where to look for the threaded barrel? Or do I just need to purchase a stock barrel and send it to someone to be threaded? Any suggestions on who to send the barrel for threading? Gem-Tech did a barrel (not a Glock) for me many years ago, and I assume would do so again, but it never hurts to learn what alternatives exist. Thanks.
