Is .40 S&W Really Dead?
Many people question the relevance of .40 S&W in today’s market. With agencies switching back to 9mm, some believe the .40 S&W is becoming obsolete. But is that really the case?
The Decline of .40 S&W – Why Did It Happen?
- 9mm Ammo Improved – With modern ballistics, 9mm hollow points now offer similar stopping power with less recoil.
- Higher Capacity in 9mm – More rounds per magazine means fewer reloads in defensive situations.
- Less Recoil in 9mm – Faster follow-up shots make 9mm easier to shoot.
- Wear & Tear on Guns – .40 S&W is harder on firearms, reducing their lifespan faster than 9mm.
Why .40 S&W is Still Relevant
- More Stopping Power – .40 S&W delivers better penetration and expansion than 9mm.
- Law Enforcement Use – Some agencies still use .40 S&W for its superior ballistics.
- More Versatile – .40 S&W can be converted to 9mm or .357 SIG with a simple barrel swap.
.40 S&W vs. 9mm vs. .45 ACP vs. 10mm
| Caliber | Recoil | Capacity | Stopping Power | Cost |
|---|---|---|---|---|
| 9mm | Low | High | Good | Cheapest |
| .40 S&W | Medium | Medium | Better than 9mm | Moderate |
| .45 ACP | High | Low | Very good | Expensive |
| 10mm | Very High | Low | Extreme | Most Expensive |
My take :
- 9mm is best for capacity and affordability
- .40 S&W is a great middle-ground with more power
- .45 ACP has legendary stopping power but low capacity
- 10mm is a powerhouse for bear defense and hunting
