I get this question quite often. It’s a tough problem to solve overnight. It takes time behind the trigger to just get your muscles use to holding a gun in your off hand. A lot of players will tend to favor their dominant hand when at the field because they don’t want to be at a disadvantage when playing. In the end this creates another disadvantage and you remain a very one dimensional player. I have a simple solution that will help you improve your ability in shooting with your off-hand and become completely ambidextrous.
How often do you watch TV or play video games similiar to COD or BF4?
For TV, anytime a commercial comes on (I mean who watches commercials now-a-days) pick up your gun and snapshoot left handed with it. If it’s COD or something similiar, anytime a loading screen or lobby comes up in between games, do the same. Grab your gun in your off hand and play around with it.
Honestly just have your gun setup in your house at all times. You’ll be surprised how often you pick it up to play around with it. Just try and to keep it in your off hand and just get your muscles use to holding it like that.
You can also start a game with your team at your field. Have you seen the silly game Impact plays called Buffalo? Anytime they catch someone drinking a beer with their dominant hand, someone calls them out saying “Buffalo!” and they have to chug the rest. Apply it to each day of paintball for a month. Any person caught holding their gun in the dominant hand while not playing, has to do 10 push-ups or some equivalent.
