There are reams of instructions about this subject, some pertain to combat shooting - LEO or military, but what I have to say is pertaining to target shooting only. One such instruction is published by the Army: http://www.bullseyepistol.com/chapter0.htm
I'm going to mention something here about trigger control for semi-auto firearms in a target shoot that some of you may be familiar with and some may not. We're all familiar with the BRASS mantra - Breath Relax Aim Slack Squeeze. Which is good as far as it goes.
Here's a question to ask yourself and that pertains to both rifle and pistol. After the first shot goes down range do you fully release the pressure on the trigger so that on the second and subsequent shots you start over again with having to take up the trigger slack? I've never seen this discussed in any instruction, but it's something I learned many years ago.
If you do, you shouldn't. You should, relatively slowly, relax pressure and allow the trigger to move forward only until you feel the sear catch with that little click. This is beneficial in that it avoids the subconscious over-relaxation of your finger, hand and forearm, and you will automatically be ready to fire the next shot with when you're on target, having bypassed the 'Slack' step.
I've found that doing this results in significantly tighter groups. Try it if you haven't. I think you'll like it.
