Springfield Armory 1911 in .45 ACP by Joe Chambers. No, not the Joe Chambers in Crete Nebraska, the Joe Chambers who was the National Guard Marksmanship Training Unit armorer. Yup, there are two of them. This precision instrument ain’t pretty, but it’s HARD fit with a Kart barrel and bushing, the later of which feels cemented in the gun. This precision tool is shod in orthopedic grips by Steve Herrett. Bullseye forever.
