10mm vs .45 vs 9mm: Which Caliber Should I Choose?

I’ve been doing a lot of research lately on different handgun calibers and I’m stuck trying to decide between 10mm, .45 ACP, and 9mm. Each caliber seems to have its own strengths and weaknesses, and I’m hoping to get some insights from you all. Here’s what I’m curious about:

Performance

  • Stopping Power: Which caliber has the best stopping power for self-defense situations? I’ve read that 10mm hits harder than the others, but is that extra power worth it?
  • Recoil: I’ve heard different things about recoil management. Is 9mm the easiest to handle, or does the .45 ACP offer a balanced shootability despite its heavier kick?
  • Accuracy: How do these calibers compare when it comes to accuracy, especially at varying distances?

Suitability for Different Applications

  • Self-Defense: Which caliber do you think is the best for home defense or concealed carry? I’m particularly concerned about penetration and over-penetration issues.
  • Hunting: I’m considering using a handgun for small game hunting. Does anyone have experience with 10mm in that context?
  • Competition: Are there any particular advantages of one caliber over the others in competitive shooting events?

Pros and Cons

I’d love to hear the pros and cons you’ve experienced with each caliber. What do you prefer and why? Maybe share some of your personal experiences with them if you own firearms chambered in 10mm, .45, or 9mm.

Recommendations

Finally, if you had to recommend one caliber over the others for someone who’s just getting into handguns, what would it be? Your insights would be really helpful as I make my decision. Thanks in advance for your advice!

When it comes to self-defense, the 10mm is often praised for its energy delivery and penetration. It can provide around 600 ft-lbs of energy, which makes it powerful compared to .45 ACP and 9mm.

That’s a great point! The .45 ACP is known for its stopping power, generally delivering around 350 ft-lbs. It might not penetrate as deep as the 10mm but can be very effective in close encounters.

The 9mm, while having less energy at about 350-400 ft-lbs, is much easier to control, making it an excellent choice for those new to shooting or for quick follow-up shots.

True! Plus, the 9mm offers a higher magazine capacity, which can be crucial in self-defense scenarios.

Consider your specific needs too. If you’re looking for home defense, penetration depth matters—it’s about stopping the threat while ensuring you don’t over-penetrate into adjacent rooms.

Absolutely! Each caliber has its strengths. The 10mm’s deeper penetration can be advantageous in certain situations, but you also have to be mindful of recoil and control.

Also, let’s not forget about ammo availability and cost. 9mm tends to be cheaper and more widely available than 10mm and .45 ACP, which is worth considering.

I’ve always been told that shot placement is the most important factor in stopping a threat, regardless of the caliber. What do you all think?

Exactly! Even a .22 in the right spot can be effective. But still, a larger caliber can give you a bit more reassurance in those high-stress situations.

I’m really torn! It’s hard to balance stopping power, recoil, and capacity. Maybe I just need to buy one of each? Haha!

Hey, that’s not a bad idea! Each caliber offers something unique. Just be prepared for a lot of practice!

When comparing 10mm, .45 ACP, and 9mm, recoil is a big factor for many shooters. The 10mm has a significant kick that can impact follow-up shot accuracy, especially for novices. In contrast, 9mm is notably manageable for all skill levels.

That’s true! I’ve found that the .45 ACP has a softer recoil than the 10mm but still provides a solid feel. It’s ideal for a more experienced shooter who can handle a bit of recoil!

I agree with bmcdowell. The 9mm is great for new shooters as the recoil is quite manageable, allowing for better follow-up shots. It might not pack as much punch, but the accuracy you gain is invaluable!

Exactly! I often encourage new shooters to start with a 9mm before moving up. It builds confidence without overwhelming them.

From my experience, some might say the 10mm is overkill, but it can be a lot of fun at the range! Just be prepared for that snap—definitely not for the faint-hearted! Anyone else feel this way?

I can see that! But I wonder how many people actually need that much power for self-defense. It’s definitely a debate!

Recoil management is crucial. The .45 ACP feels powerful but almost comforting with its slow push, while 10mm can surprise you with its intensity. For competitive shooting, I stick to 9mm for its speed and control.

I like the sound of that! It seems like shooting sports truly favors the 9mm for its lesser recoil, keeping us fast and accurate!
