I am building a PCC 9mm for competition. I am down in choosing the barrel. I am looking at between the Faxon 16in with the integral muzzle brake, kaw valley 16in, taccom 13/16 superfeed, JP ent 16in and the rainier arms ultramatch. For the brake I’ll be using the coda. Any comments are welcome. It will be mounted on the spikes tactical gen ll upper and lower kit with the Mbx buffer kit and taccom bcg.
