Les Baer Custom: High-Peformance M1911s | An Official Journal Of The NRA
Les Baer began tuning, fixing and modifying guns in 1973. His first shop, so to speak, was the basement of his home in Allentown, Penn. Enthusiasts quickly discovered the quality of his work and word spread. By 1976 demand was outgrowing his workspace, forcing him to expand. In 1980 he launched his full-time gunsmithing career by establishing Bear Custom Guns.
