What started out life as a regular ol 1911 now has a few mods. I don't know who made the parts, but it has a bushingless barrel with 2 port comp, full length guide rod, extended slide release, checkered flat mainspring housing, Pachmayr wrap around grips, and a three hole trigger with overtravel screw. Crisp, but not extremely light trigger. Have gun, case, box, and all the paperwork it came with new. 4 Mags total, 3 of them Shooting Star, all with bumper pads. Just found more paperwork that goes with this gun. Was purchased new in 1990 and all of the parts purchased and installed by Shooters Service Center.
