Retention Shooting | Private Class with Craig Douglas
This guide details the Thumb Pectoral Index (TPI) retention shooting technique taught by Craig Douglas of ShivWorks. TPI is designed for extreme close-quarters scenarios (within three yards) to ensure consistent shot placement, prevent self-injury, and maintain weapon control during a struggle. The technique emphasizes a flagged thumb, locked wrist, and high elbow to create a stable shooting platform and allow for slide cycling. Instruction includes live-fire drills and transitions to appropriate extension based on threat distance.
