Sorry I took so long to answer you . The Custom work was all done by SACS ( Springfield Armory Custom Shop )
I always wanted a Commander size pistol for carry . I wanted a 9mm 1911 and I wanted a bobtail 1911 . So I put all
the things I wanted into one pistol . SACS machine checkered the front strap 25LPI , Bobtail it , reworked the grips
to fit ( Awesome sanding job ) , Colt high cut the trigger guard , Trigger job 4.0 lbs , Cerakote frame & slide . They
had a Reliability Package " when they were a full service shop " That was done . Its a fun little light pistol to shoot .
Thank you for your interest . I'am a SACS Fan Boy . Also I believe ALL 1911's should have front strap checkering .
