Commercial Pistols covers M45A1-pattern Colt 1911s sold to civilian buyers, separate from the FOIA-documented decomm fleet. Since there's no government custody record for this population, research here is built differently — from observed examples rather than logistics data: finish types, frame and slide colors, serial ranges, and known variations, each cross-referenced and confidence-tiered as evidence allows. That work is in progress. Check back soon, or use Lookup if you already have a serial.
