Quite simply Aris. When you want a conventional trigger to fire, you pull it. When using a release trigger you pull it, then wait utill you are ready to fire, holding pressure on the trigger to prevent it from firing. It's like holding a hand grenade with the pin out, and from that point onwards, you've got to throw it somewhere. Personally I don't touch my trigger until I want to fire because I know what happens when I do.
When you've seen what can happen, even to an experienced shot, I think you may change your mind. It sounds like you've not been around them much and seen what can go wrong yet? I hope you never do!
