Choosing the right concealed carry pistol is a deeply personal decision, hinging on factors like hand size, shooting experience, and desired level of stopping power. Two popular contenders often top the list: the Sig Sauer P365 in 9mm and the Sig Sauer P365 .380 ACP. Both offer similar ergonomics and reliability within the Sig Sauer ecosystem, but their differences in caliber significantly impact their performance and suitability for self-defense. This in-depth comparison will help you decide which pistol best fits your needs.
Caliber Showdown: 9mm vs .380 ACP
The most significant difference between the Sig P365 9mm and .380 lies in their calibers. This impacts several key aspects:
9mm (9x19mm Parabellum):
- Stopping Power: Generally considered to have superior stopping power compared to .380 ACP. The larger bullet diameter and higher energy transfer result in greater wound cavities and a higher likelihood of incapacitating an attacker.
- Penetration: 9mm rounds offer better penetration through barriers like clothing and car doors, crucial in self-defense situations.
- Recoil: Experienced shooters typically find 9mm recoil manageable, especially in a lightweight pistol like the P365. However, beginners might find it slightly snappier than .380.
- Ammunition Availability: 9mm is widely available and affordable, making it easier to stock up on ammunition.
** .380 ACP (9x17mm):**
- Stopping Power: .380 ACP has lower stopping power than 9mm. While still capable of self-defense, its smaller bullet and lower energy transfer might require more accurate shot placement for effective incapacitation.
- Penetration: Penetration is generally less than 9mm, potentially limiting effectiveness against thicker barriers.
- Recoil: Significantly less recoil than 9mm, making it easier to control, particularly for smaller-framed individuals or new shooters.
- Ammunition Availability: Readily available, though potentially slightly more expensive and less diverse in terms of bullet types than 9mm.
