Handgun. Pretty common. It's a good starting point. A lot of other guns require you adjust for recoil or special priorities the bullets contain. A lot of them trade accuracy for power too unless you know how to make up for the difference. Guns are about aim, but it's also about knowing how to hold your body. It's easier to show in person. It'll probably take me a month to get a place and get everything set up, but since you might be working there, I want to see your style before then.
i.e. i have to wait a month to use the license
