Hey all, I'm looking to buy my first firearm, and at 20, I'm still limited to a rifle. This is not a problem as I would prefer a rifle. I'm looking for a .22 as everyone I talk to says to get a .22. Being a lefty tho, Im not sure if I need aa left handed rifle or not. I was looking at a ruger 10 22. Are they ambidextrous, or am I going to need a left handed model?
