Competitive shooting can help develop skills that are useful for defensive situations, but it shouldn't replace self-defense training:
Gun handling: Competition shooting can help improve grip, draw, presentation, mechanical manipulations, and retaining control of the gun.
Marksmanship: Competition shooting can help improve marksmanship skills.
Mindset and decision making: Competitive shooting can help develop making quick shots under stress.
Stress training: Competition shooting can help you learn to think and react in high-pressure situations.
Real-life situations: Competition shooting can put you in situations you might not otherwise encounter, which can help you prepare for real life.
