One of the most common issues that plagues new shooters is grip and trigger mechanics. Your grip and trigger pull have a tremendous impact on your accuracy by generating muzzle movement. Over the years I have heard a lot of instructors teach the 60/40 or the 40/60 split force rule. Meaning, you should grip the firearm using 60% strength with your dominant hand, and provide a resistance back pressure of 40% with your support hand and vice versa for recoil management. I personally subscribe to the 100% theory. As a kid, playing sports, my coaches always told me to practice like I play. The same advice is directly applicable to shooting. In a self-defense situation you are not going to be thinking 60/40 or 40/60. You are going to purchase that firearm from its holster, grip it as tightly as possible, and discharge it towards the threat. You should practice with your firearm in the very same manner.
The trigger mechanics, in my opinion, is far less important. You will probably hear a lot about finger placement. From my experience, every shooter is different. I have found, that with good grip mechanics, finger placement on the trigger becomes negligible. With a good grip on the firearm “slapping the trigger” will not result in impacting muzzle movement. Your focus should be more on keeping a firm and consistent grip. Improper grip mechanics will become more noticeable the farther the distance to the targets. As you work to improve your mechanics, you should push your targets out as well. Here are ten simple tips that will help to greatly improve your grip mechanics.
1. Your primary hand should be as high up on the beaver tail as possible.
2. Keep a firm grip on the firearm at all times. A varying grip will result in muzzle movement and accuracy issues. A lot of people tend to have a loose grip when lining up the sights and then they'll tighten their grip at the last moment in anticipation of the recoil.
3. Recoil will take the path of least resistance, for this reason two hands are always better than one. Make sure you leave no gaps between your dominant and support hand.
4. For better recoil management and absorption you'll want a full extension of your arms.
5. Limit your wrist movement. One common issue with accuracy is “limp wristing”.
6. The thumb on your support hand should ride parallel with your trigger finger. This provides balance and will assist with proper alignment.
7. Practice with a tight grip. One simple way to practice at home is coin drills. Balance a coin on the end of you firearm. You should be able to dry fire without the coin falling off.
