As far as formal paid instruction; Im an instructor for TDSA, period. I credit my brotherhood and training with them (mostly as a paying student) with a very large part of where I am today. Call it success, status, whatever. I wont accept any money for training a group of guys, or putting on a class.
two big reasons;
1. because it wont be as thorough as a tdsa class, or have the wide base of knowledge you get from having multiple instructors working in a proven format such as AP1.
2.Im not going to compete with TDSA, and give folks an option instead of TDSA.
I dont mean that to sound anti-trust or anything, I know its a monetary and time sacrifice, you may piss off a wife or girlfriend or boss, and you might not get to buy the new magpul tactical battlefarker or XDm 6.8 Grendel, but whether I give someone a gun I built or whether I recommend training, I only settle for the absolute best I can get you.
