I am new to competitive shooting. I started with a Glock 19, and one problem I had was occasionally pulling off a second shot unintentionally. After some practice I was able to alleviate the problem with the Glock. Recently bought a CZ shadow 2 and still getting used to it. I have the same problem with the CZ as I had with the Glock and I am pulling off a second round sometimes. Any suggestions for practice would be appreciated.
