You probably spent quite a lot of time and effort finding the gun that you like best for concealed carry. It fits your hands, you shoot it well, it's durable, and you can conceal it well. But is that one gun the only gun you will ever need? Maybe not.
Your favorite suit is sharp and you look like a million bucks in it. But it's not appropriate to wear when you're mowing your lawn, right?
Similarly, situations arise where better options than your favorite concealed carry piece exist.
Home Defense Gun(s)-
I highly recommend everyone have a firearm dedicated to protecting the home. This may be your concealed carry gun, but ideally, another gun should fill this need.
Based on your specific situation, you may choose a rifle, shotgun or handgun to defend your home. They all have strengths and limitations that you should carefully weigh.
A few questions you may want to think about when deciding are:
-Who else lives in your home
-Do you live in an apartment and share walls with neighbors
-How large is your home
-Who else will be using the gun
-Can you attach a light to the gun
-What is the capacity
Even if you carry your firearm inside your home, what happens when you are gone? What if you have a family member who isn't always carrying a gun and they are home alone?
What about multiple guns? While answering the above questions, you may realize that having guns in various parts of the house is a good strategy. If you have a multi-level home or a large ranch style layout, your one home defense gun may not be easily accessible.
In fact, you may find that based on the location of the home, a different type of gun works best.
Back Up Gun (BUG)-
There are situations that may drive you to carry a firearm in addition to your primary everyday carry (EDC) gun. Typically this backup gun is not just a duplicate of your primary piece. Why?
Backup guns are usually smaller and carried in another location on the body, like the ankle. Because of this, your back up gun is probably going to have less capacity, and possibly a smaller caliber as well.
The features you look for in a backup gun are not going to be the same as what you want for your EDC.
I know there are some who shoot their concealed carry gun in their competitions. Depending on what type of competitions you are competing in, this may not be the best practice.
Some of the modifications done to competition guns are not helpful on a concealed carry gun. For example, super aggressive grips can be great in a competition, but on your EDC can snag on clothing and rub skin raw.
Because larger guns are easier to shoot, full-size handguns are more appropriate for competitive use when compared to the sub-compacts for concealed carry.
Also, think about what happens if your competition gun breaks or has a part wear out. Now you are without a firearm for daily protection.
If you happen to carry a firearm for work, and it doesn't have to be concealed, you're probably going to want a duty sized firearm. Why, if for no other reason than capacity.
If you have a job where being armed is a necessity, you definitely want to have as much capacity and caliber as you can manage.
When I was a police officer I got issued a Glock 22. This drove me to the Glock 27 for my off-duty choice. There would be no way I could conceal a G22, and similarly, I would never have carried a G27 as my duty weapon.
I know many people who carry a sidearm in addition to their rifle while they are hunting. Maybe you carry for protection against shady people you may come across, or maybe in case of a run-in with an aggressive animal at close range.
Either case, concealing your firearm is not a concern. So you are going to want to carry something large enough to stop whatever beast you may come across in the wild.
What It Boils Down To-
Having the right tool for the job. Can you get away with using your EDC for all of the above-mentioned situations? Absolutely, but there are better options that may be more appropriate.
