.400 corbon bbl for 1911 5" bbl this will fit any standard 1911 .45 and the .45 mags will work with the .400 I paid $70 for bbl but will take $50 shipped. Or make an offer the barrle has less than fifty rds. through it. I used it with my Ballester Molina but had feed ramp problems. I was told the colt and clones would feed better than my ballester, I didn't want to alter my gun permantely by polishing the feed ramp I was afraid I wouldn't be able to switch back to .45 I prefer paypal my account is at email@example.com or you can send money order to me.
