Welcome to the forum. For a first gun, you may want to try something a little easier to shoot, like a .22LR pistol or revolver, or even a 9mm pistol. Find a gun range that lets you rent guns, and try a few to see what works for you. Keep in mind that if you go with a .22 or 9mm, ammo will also be a lot chaeper, so you can shoot more for the same money.

"In the end more than they wanted freedom, they wanted security. When the Athenians finally wanted not to give to society but for society to give to them, when the freedom they wished for was freedom from responsibility, then Athens ceased to be free." - Edward Gibbon
