If you are "timing the gun" then a dive when you hit the snapcap might not actually be a problem.

Stance - Check your stance and make sure you are keeping weight forward to help with recoil management. I see a lot of shooters that stand straight up, or even lean back, which is not conducive to managing recoil and can send rounds high. Think of a football player making a tackle, his weight is forward, and his legs are spread and have some flex to absorb impact. Shooters need to use the same concept.
Grip - Check your support hand. Get as high on the gun as you can, and remember that the support hand supports most of the weight of the gun, while the strong hand runs the fire control systems. You may be losing contact with your support hand when the shot breaks due to a weak grip, or breaking your wrists.
Trigger control - Use the part of your trigger finger that gives you enough leverage to press the trigger straight back to the rear without pushing the gun to the left (not enough trigger finger), or pulling it to the right (too much). The "sweet spot" is different for everyone due to finger length, hand size, and strength, so you have to experiment to find out what works best for you.
Follow through - Make sure you are trying to apply the fundamentals before, during, and after the shot breaks. You should maintain your focus on the front sight and watch it settle back into position at the same spot on your target. A lot of shooters seem to just mentally quit as soon as the round breaks, but if you maintain that mental focus, your groups will be tighter.
A couple of drills:
Ball / dummy drill - Look away and have your partner prep your gun with either a live round or empty chamber without you knowing which. Step up, focus on the fundamentals, and take the shot. If you are doing your part, the gun won't jump, or dive when you fire on an empty chamber, and if you do, you will know what you need to work on.
Laser dry fire - Get a cheap laser bore sighter and use it to due dry fire drills. Focus on keeping that laser on the exact same spot before, during, and after you break off your shot.
