Flinching, jumping, or blinking are all totally normal reactions to gunshots. If you are new to shooting don't worry if you can't help but react to the noise and recoil of firearms, that is totally normal! 

A simple par timer can make a huge difference in your training. 

This was my students first time shooting a plate rack and she did great! Practice and hard work pays off!

Don't build bad habits during your dryfire practice! Keep that support hand strong. You will shoot how you train so train how you want to shoot!

Keeping a natural and comfortable posture will help you build consistency and make shooting more enjoyable.
