Frequently Asked Questions

What is the primary reason to avoid +P+ ammunition?

The main reason to avoid +P+ ammunition is the excessive pressure it generates, which can over-stress your firearm, potentially leading to damage or reduced reliability. It's generally considered hotter than necessary for most practical applications.

What are better alternatives to +P+ ammunition?

Instead of relying on +P+ ammunition, consider choosing a more powerful caliber like .40 S&W, 10mm, or .357 Magnum. If you prefer 9mm, sticking to standard or +P loads is generally recommended for firearm longevity and safety.

Can using +P+ ammunition damage my firearm?

Yes, using +P+ ammunition can definitely damage your firearm. The significantly higher pressures can exceed the design tolerances of many guns, leading to premature wear, component failure, or even catastrophic malfunction.

When might +P+ ammunition be considered?

+P+ ammunition might be considered for calibers like 9mm Luger when maximum power is absolutely essential and the firearm is specifically rated to handle such high pressures. However, it's generally advised to explore other options first.
