Slow is smooth, smooth is fast, speed will come with time. As well as consistent head shots.
Thank You for a great web site for S&W fans. I am a currently unemployed LEO in Southern WI, back in college for my bachelor's degree, and currently doing the hiring processes for a couple different agencies. I am a Glock Armorer and certified by the Massad Ayoob Group. Any training...
