Choosing the best caliber for concealed carry can be overwhelming, especially for new gun owners. With so many options on the market, how do you decide between 9mm, .380 ACP, .45 ACP, .40 S&W, and even .38 Special? Each caliber has strengths and trade-offs when it comes to size, stopping power, recoil, and ease of concealment. Let’s break down the most popular calibers to help you choose the best option for your needs.
9mm: The Most Popular Caliber for Concealed Carry
The 9mm is easily the most common and recommended caliber for concealed carry. It offers the best balance of power, capacity, and shootability, making it the top choice among law enforcement and civilian carriers alike.
Pros:
- Manageable recoil for most shooters
- Wide selection of guns for concealed carry
- Affordable and widely available ammo
- Higher capacity magazines compared to larger calibers
Cons:
- Some argue it offers less stopping power than .45 ACP (though modern ammo tech has largely closed this gap)
If you carry a 9mm handgun, you'll need a reliable IWB holster or OWB holster to stay discreet and comfortable. The Breakout 1.0 IWB Holster and Breakout 2.0 IWB Holster are perfect options to keep your carry secure without sacrificing draw speed or concealment.
.380 ACP: Lightweight and Easy to Carry
The .380 ACP is popular with carriers looking for small, lightweight pistols that are easy to conceal. While it's a step down in power from 9mm, it's easier to manage for those sensitive to recoil.
Pros:
- Minimal recoil
- Compact gun size for deep concealment
- Easier to control for beginners
Cons:
- Lower stopping power
- Shorter effective range
- Can be pricier per round
Many ultra-compact .380 ACP pistols pair well with a minimalist IWB holster for maximum comfort. Check out the Breakout 1.0 IWB Holster for everyday concealed carry comfort.
.45 ACP: Heavy-Hitting Power
The .45 ACP is known for its stopping power and is favored by those who prefer larger calibers for self-defense. It produces a slower, heavier bullet with strong impact.
Pros:
- High stopping power
- Proven track record for defense
Cons:
- Heavier recoil
- Lower magazine capacity
- Bulkier guns
A good OWB holster is essential when carrying a full-size .45 ACP pistol. The Breakout 1.0 OWB Holster provides ergonomic comfort and concealment without printing.
.40 S&W: The Middle Ground
Once the dominant law enforcement caliber, .40 S&W sits between 9mm and .45 ACP in terms of power and recoil. It's a solid choice for those wanting more punch than a 9mm but a smaller frame than .45 ACP.
Pros:
- More stopping power than 9mm
- Available in many compact handguns
Cons:
- Sharper recoil than both 9mm and .45 ACP
- More wear on guns over time
.40 S&W is well-suited for carriers who want added power but need to stay within a compact footprint. Pair your .40 with an IWB holster for better concealment.
.38 Special: The Classic Revolver Round
For fans of revolvers, the .38 Special is the go-to concealed carry caliber. It's easy to shoot, reliable, and has stood the test of time.
Pros:
- Mild recoil
- Excellent accuracy in snub-nose revolvers
- Reliable and simple to operate
Cons:
- Limited ammo capacity (usually 5 or 6 rounds)
- Slower reloads compared to semi-autos
If you carry a revolver, a quality revolver holster is critical. Houdini Holsters offers excellent options for both revolver holster OWB and revolver holster IWB setups to keep your firearm secure and accessible.
