If you are buying your first gun, then you should seriously consider going to the gun shop. There are many advantages of going to a gun shop that you will want to be aware of. Here is more on gun shops and why first-time gun buyers should make a point of going to one.
You can see a lot of guns in person
When you are buying your first gun you may not have any idea what gun you should get. If you were to purchase a gun online that seems like it would be right for you, then you might find out that it is uncomfortable in your hand, that it's bigger or smaller than you thought, that it's too heavy, or that you can't even grip it in a way that feels secure. When you are at a gun shop, you get to look, touch, and hold all the different guns. When you buy from the gun store, you know what you are getting and you already have an idea of how you will like it.
You can learn a lot about any guns you are interested in
When you go to the gun shop, you can learn about all the guns you are considering so you can make an educated purchase. You can also ask questions about any guns you think you may want to purchase in the future. A gun shop is a great place to take advantage of the staff's knowledge.
You can purchase all your accessories
When you are getting your first gun, you may have no idea what accessories you will want or need to get with it. When you go to the gun shop, you can learn all about the necessary and useful accessories that might come with it at the same time. You can look at the different options and buy what you like right then and there.
You can take advantage of classes
Most gun shops will hold classes. The number and type of classes each gun shop may offer differs greatly, but most of the shops that do hold classes will have some for beginners. You should take advantage of this and attend classes. This way, you know that you are going to end up being a more competent and safe gun owner. They can often help you to get your concealed weapons permit if this is also something that you're interested in.
