Get a grip exercizer thing that they sell for guitarists. It will let you flex each finger individually against a spring so you can practice clinching 3 fingers without inadvertently moving your index finger.
Get more power from your stance, I like to turn almost completely sideways to the target. I let the recoil drive from my locked arm into my tensed shoulder and down to my rear leg.
I do not cant the gun but some people (good shooters I might add) find that helps.
Some people like to tense their other hand against their chest. I see Mas Ayoob doing this and others, but personally I put my off-hand hooked on my pocket or belt.
