Welcome. I have been learning a lot here. Utah has a lot of really great laws for guns. I would suggest taking some of the CFP or other training courses available here. There is a lot of good information and no reason to get more familiar with a firearm before taking the class. There are also some basic training classes from what I have seen. Although money can be an issue, and I completely understand that. Glad you are getting back on your feet.
