I came across this listing recently for some 9mm +P solid copper hollow point in 50rd boxes at One Source Tactical. It apparently is a private-label job from Cor-Bon (DPX projectiles) for One Source, who markets it as “TSD Combat Systems” 9mm. I would imagine the headstamp is typical Cor Bon. This has been around for about 2 years based on an announcement of it’s arrival being posted in a forum from Dec, 2012.
One Source Tactical is the retail website for Suarez International, run by Gabe Suarez (Google him). “TSD Combat Systems” is some component of Suarez in terms of branding via One Source. Suarez International also runs the Warrior Talk forum, which in my personal experience was one of the most elitist and unpleasant forums I had ever been in.
