Cowboy Gun Works

Jim McMahon, known as 'Jimmy Spurs,' runs Cowboy Gun Works as a full-time gunsmith specializing in competition firearms—particularly Cowboy Action Shooting (CAS) and Cowboy Fast Draw Association revolvers.

He recently came out of retirement to win the 2025 SASS VT State Championship.
