I shoot USPSA (United States Practical Shooting Association). I, obviously, got to shoot lots and lots during my military career. I find shooting USPSA to be a fun and challenging hobby. You work on accuracy, movement, magazine changes, and safe handling of a firearm while moving. The safety aspect is the most important.
There are lots of videos on youtube, if you want to check it out.

There are so many ways that you can enjoy shooting. You just need to find what appeals to you.

JYL, my suggestion would be to shoot with both hands while you get your grouping tighter and more consistant. Once you have established that, then try single hand shooting. Also, optics should be used with both eyes open. It is a bit of a transition that I went through going from open sights to red dot. You might already use both eyes, but I just threw that out there in case.

Good luck and happy shooting !
