Handgun Combat Master
Designed by Chuck Taylor, the Master training regimen and test is the most difficult handgun discipline in existence.
The student will learn to present the pistol and shoot accurately in extremely compressed times - he must be very fast and very accurate. Most students take years to pass this demanding protocol.
If you want to push handgun shooting to the top, the Master's program is the way to go. You cannot pass this alone - the student can only be certified when an existing Master tests him.
