What gun should I get?

I've recently become very interesting in shooting! It started a few years ago when I was practicing with a compound bow and decided I needed to go one step further and try a gun! I've done the work to get my license and my restricted as well (I'm in Canada). I'm a member of the local range and have tried out a few different guns now. I've shot my friends Kel-Tec SU16 and loved it, and recently tried his Smith and Wesson 9mm handgun. I thought they both felt great. The .22 I shot is shown at the bottom and was too easy. I was hoping to see if I could get any other suggestions?
