One of the nice things I am learning about my new to me PT99 is how predictable the double action break is. I can easily pull back to single action distance and hold there until I wish to fire. So nice. The trigger provides enough feedback in double action to know exactly where the break is with very little practice. And the single action break is so clean. I bought the gun and used it for my very first practical pistol shoot the next day. The gun is that easy to learn.
