Hunting PurposesIf you like to hunt, having an array of guns to choose from is important. You can shoot different animals using different firearms. Rifles are generally used for long-range or bigger animals. Shotguns are used generally for birds and smaller varmints. You should use what you feel most comfortable with when you go out.
Defense PurposesWith criminal activity happening all over, many people look for ways that provide them with self-defense. Some people will get security systems or other non-lethal alternatives. Others will choose to purchase a gun. You can use almost any gun for defense if you need it. Make sure you practice shooting it though so that you are comfortable if you ever need to use it.
Tournament PurposesMany people like to get competitive with their shooting skills. People will go through a course and shoot competition handguns to obtain a better score. Things like accuracy and time are judged and included in the final numbers. As you do this more and more, you will get better. Every course will have its differences, so make sure you feel comfortable with your firearm to score the best.
Hobby PurposesSome people just like to collect guns as a hobby. There are different calibers, sizes, brands, and styles they can choose from, including old or new guns. Many people like to find firearms that are hundreds of years old, as they are valuable because of their limited availability. Although you may find that more modern styles are what you want to collect.
When purchasing your gun, keep safety in mind. Have fun using them, but make sure you have places to lock your firearms up so there are no accidents.
