INITIAL CONSIDERATIONS
Before we get into choosing the right size, style and caliber, there are some decisions about features, specifications and accessories you need to make.
GRIP LENGTH, THICKNESS AND WEIGHT
When looking at handguns for carry, you will want to consider the grip size, thickness and loaded weight, because these are the primary factors that will determine how easy it is to carry for you.
Thicker guns and guns with a longer grip tend to print (when the outline of your firearm can be seen under your clothing) more, and depending on your local laws, this could be a legal issue. Printing is also something a lot of first-time concealed carriers are concerned with and if your gun prints too much, you may feel uncomfortable having it on you.
HOLSTER AND CARRY POSITIONS
You will also want to consider what type of accessories you want. Primarily, you are going to need a holster if you are going to carry properly, and some gun models are easier to find holsters for than others.
Some of the more common handguns from companies like Springfield Armory or Smith and Wesson are going to have a ton of options, whereas some older or more obscure models may not. When selecting a holster, you need to decide on where on your body you plan to carry your firearm.
There are pocket holsters, shoulder holsters, outside-the-waistband holsters and more, but the most popular for concealed carry are probably inside-the-waistband holsters. These holsters tuck inside your pants and clip to your belt and are a good balance between accessibility and concealment.
