About Us

In business since 2005, based on research and development going back another 5 years, SJC's mission is to provide the shooters using our products with a competitive advantage in an economical package.

John Nagel and Steave Breeding are co-founders of S & J Customs (SJC).


John is SJC's primary gunsmith and a highly trained machinist. John has been formulating open/race GLOCK guns since 2000 to achieve perfection and reliability. Now working with other pistol and rifle platforms, John not only builds winning guns but designs accessories which will improve the performance of your firearm, including the SJC Titan compensator.

John is a Former National Champion Kart Racer, but now puts his competitive drive into building and shooting the ultimate competition pistols. John is a Grand Master in USPSA/SCSA for RFRI (Rimfire Rifle Iron Sights), RFRO (Rimfire Rifle Open Sights), RFPO (Rimfire Pistol Open) and has been on the award podium more than 30 times in state, regional and international events.

Steave is SJC's primary business and sales guide, but also works on all parts associated with the frames of the SJC pistols. Steave is a doctor of Veterinary Medicine graduated from the University of Georgia. He has shot many different disciplines over the years and loves all of them. However, practical pistol shooting seems to have taken over. Steave is currently a USPSA member shooting Production (B), Limited 10 (B), Limited (B), and Open (C). Steave lives to compete. DVC
