OK, I'll Wade in...
#1. Grip, the gun has GOT to fit your hand.. you should establish a grip that is consistant and repeatable... it shuld be instinctive.. meaning that when you bring the sight UP to your eye level, (don't dip your head to find the sights) the sights are there.. I teach to start with eyes closed, bring the gun into position, open your eyes and you have a sight picture... you may need to slightly shift your feet to align with the target.. this takes a lot of stress off of your upper body and allows you to concentrate upon what it important... controlling the trigger...
More on the grip,, a two handed grip, with strong hand wrapping around the pistol, thumb laid down, the supporting hand should come from around the strong hand. If right handed the left hand should come from about your knuckles and drag over your right hand fingers, slightly pulling at the skin on top of your fingers until you wrap all the way around, locking your weak (left) hand thumb over the top of your right hand thumb.. Pressure, should be firm, but not fatiguing.. the majority of the gripping strength coming from your left hand. The right hand is supporting, and controlling the firearm. the lock is with the left hand, but NOT white knuckled !!!!
Start with a GOOD trigger job... the trigger should be SMOOTH,,, ribbed triggers are a hindrance... There should be no creep in the trigger, I personally do NOT like staged triggers.. should be a smooth continuous pull... vary pressure while maintaining sight picture.. as the sight drifts into alignment, increase pressure.. When the gun goes off, it should be a surprise... Exact finger placement on the trigger will vary, with speed, level of accuatcy, pistol size, trigger width, and your own hand size and comfort level... For me, finger tips do not work, sinking it in to the last knuckle doesn't work, I'm good somewhere between the 1st and 2nd knuckle..
There are drills that you can do to increase speed and fluid movement of the trigger.. I found one on you tube that is what we learned years ago..

HA HA.. I realized by looking at the poster of this video that it is none other than our own, Mr. Borland... he is good,, and he shows off a bit at the end.. Good post Mr Borland.. !!
Please note the speed, smoothness and control that can be achieved. this does not happen overnite, but it does happen, only with practice... remember, only Proper Practice makes Perfect...
Take it slow, NOBODY got this right overnite... It is a system and a platform,,
Bruce Lee once made the statement, "I do not fear the man that knows 10,000 kicks. I fear the man who has practiced one kick 10,000 times... "
Practice... Practice... Practice....
