I have a new 9mm comp. barrel for my old Whizbang Thunderthumper, and I'm looking to finish the short chamber now that the barrel has been fitted to the slide.
I know this is oldish thread, but can I ask where you got yours from and how do you like it? I've got a couple of barrels that struggle with HP loads due to tight throat. I've been eyeing the brownells one. TIA
