.40 S&W vs 9mm: Which Should I Choose for Self-Defense?

Introduction

I’m in the market for a new handgun and I’m really torn between the .40 S&W and the 9mm. I’ve done some reading, but I want to hear from those who’ve actually used both calibers.

Performance and Characteristics

  • Recoil: How does the recoil compare between the two? I’ve heard the .40 has a bit more kick, which might affect follow-up shots.
  • Ammunition Capacity: I’m also considering magazine capacity. Is the 9mm significantly better in that regard, or is it not a dealbreaker?
  • Lethality & Penetration: I’ve seen arguments for both sides regarding stopping power. What have your experiences been in real situations?

Suitability for Self-Defense

  • Which caliber would you recommend for everyday carry?
  • Are there specific scenarios in which one caliber shines over the other, particularly in law enforcement settings?

I appreciate any insights or personal experiences! I’m looking to make an informed decision based on reliability and effectiveness.

Great topic! The .40 S&W typically has a higher velocity and energy transfer than the 9mm, which can lead to more effective stopping power in self-defense situations. However, it also has more recoil, which can affect follow-up shots.

True, but the 9mm has improved quite a bit in terms of expansion and penetration thanks to modern ammunition technology. It’s definitely worth considering for self-defense.

Ballistic performance aside, also think about how you shoot. The .40 can be snappier and may slow you down in a defensive scenario. Comfort and control are key!

Absolutely! A well-placed shot with a 9mm may be more effective in high-stress situations due to reduced recoil.

You guys make good points. For those new to shooting or self-defense, starting with a 9mm can help build confidence and skill before moving to something like .40 S&W.

That said, if you’re comfortable with the .40 and can shoot it accurately, it definitely has the benefit of heavier rounds for stopping power. It’s all about personal preference and what you shoot best!

Speaking of preference, how do you feel about the recoil? I’ve heard some say the .40 is harder to manage than the 9mm, especially for rapid fire.

That’s true! I always tell new shooters to try both at the range. You’ll feel the difference and know what feels right for you.

.40 S&W does have a leg up on penetration, but if we look at the stats, a 9mm can deliver nearly similar performance with less recoil. Something to consider for self-defense!

Exactly! Plus, 9mm ammo usually costs less, which is a key factor for regular practice. Who doesn’t love more range time?

I wonder how factors like personal ability and ergonomics of the firearm impact this decision too. Anyone here made the switch from one caliber to the other?

I went from .40 to 9mm and found it much easier to manage. It allowed for better accuracy and speed in my shooting. Sometimes comfort trumps power!

I’ve had experience with both calibers. The .40 S&W has a stronger recoil which can be a bit harder to manage for new shooters. In contrast, the 9mm feels more comfortable and easier to control during rapid fire. It really comes down to what you feel more confident shooting.

I totally agree! As a new shooter, I found the 9mm much easier to handle. Not only is the recoil lighter, but you can get back on target faster, which is crucial in a self-defense scenario.

A lot of people say that the .40 has more stopping power, but comfort and control are key. If you’re not able to shoot accurately because the recoil is too harsh, it undermines that ‘stopping power’.

Right! I think that’s a major point to consider for anyone new to firearms. The best caliber is one you can shoot confidently! What are your thoughts on the ammunition cost difference?

That’s an excellent point! 9mm rounds are typically cheaper and more readily available too, which is a significant factor for practice. Practicing with the caliber you intend to carry can improve your comfort level immensely.

Absolutely! It’s important to be well-practiced. And hey, at the end of the day, shooting should be fun too! Which caliber gives you that extra thrill?

From my experience, the .40 gives a nice pop that feels powerful, almost like you’re holding a beast! But stick with what’s comfortable for you. Every shooter has their own preference and experience level.
