Yes, you can use 33-round magazines in 3 gun competition. There are no restrictions on the type or size of the magazine that you can use in 3 gun competition. However, keep in mind that some stages may have a limit on the number of rounds that you can fire, so it is important to check the rules before using a high-capacity magazine.
Additionally, using a higher-capacity magazine may not always be advantageous, as it can add extra weight to your gun and make it more difficult to handle. Ultimately, it is up to the shooter to decide what type of magazines they want to use in the competition.
