Choosing the right ammunition for everyday carry isn’t complicated—but it directly impacts performance, safety, and liability. The round you load into your firearm should be selected with intent.

This is not the place to cut corners.

The Short Answer:

For everyday self-defense, you should carry:

Quality factory defensive ammunition—specifically Jacketed Hollow Points (JHP) or equivalent—from a reputable manufacturer.

Not range ammo. Not reloads. Not gimmicks..

What Is Defensive Ammo?

Jacketed Hollow Point (JHP)

JHP ammunition is designed for defensive use. It is built to:

• Expand on impact
• Transfer energy efficiently
• Reduce overpenetration

When a JHP expands, it creates a larger wound channel and slows down faster. That combination helps stop a threat while reducing risk beyond the target.

Why Defensive Ammo Matters (Even If You Miss)

If you miss your intended target, your ammo choice still matters.

JHP (defensive ammo):

• Expands and slows down on impact
• Dissipates energy faster when hitting walls, floors, or other barriers
• Reduces risk to others beyond the target

FMJ (range ammo):

• Maintains shape and penetrates
• Carries energy farther after a miss
• Higher risk of passing through walls or continuing unpredictably

There’s also a stopping performance issue:

• JHP is more effective at stopping a threat
• Often requires fewer rounds (2–3) in a justified defensive scenario
• FMJ may require more rounds (5–6 or more) due to limited expansion

Bottom line:
You want ammo that is effective on the threat and safer beyond it.

What You Should NOT Carry

Full Metal Jacket (FMJ)

FMJ is for training—not for self-defense.

• Designed for penetration, not stopping threats
• Higher risk of overpenetration
• Less effective terminal performance

Reloads / Handloads

Do not carry reloads.

• Inconsistent performance
• Reliability concerns
• Potential legal complications

Factory ammo removes doubt. That matters.

“Gimmick” Ammo (Including RIP Rounds)

Avoid novelty or heavily marketed rounds.

One specific example is the RIP (Rapidly Invasive Projectile) round.

I do not recommend carrying it.

From a performance standpoint:

• Not widely used by law enforcement
• Does not consistently meet FBI ballistic standards
• Questionable real-world effectiveness

But the bigger issue is legal defensibility.

If you’re involved in a shooting, you may have to justify your decisions to a jury.

It is much easier to explain:
“I carried standard law enforcement-grade defensive ammo”

Than it is to explain:
“I chose an extreme, highly marketed round designed to do maximum damage”

Personally, I would not want to sit in front of 12 jurors and try to justify carrying something like that.

That’s why I call it:

“The rest in prison round.”

Stick with proven ammo. It performs better—and it’s easier to defend legally.

What Makes Good Defensive Ammo?

Look for ammunition that meets FBI ballistic standards:

• 12–18 inches of penetration
• Reliable expansion
• Consistent performance through barriers (like clothing)

This ensures your ammo works under real-world conditions—not just ideal ones.

Proven Defensive Ammo Options

Stick with duty-proven, widely accepted loads:

• Federal HST
• Speer Gold Dot
• Hornady Critical Duty / Critical Defense

These are:

• Used by law enforcement
• Extensively tested
• Reliable across platforms

My Personal Pick

One of my personal favorites is:

147 grain Underwood +P+ (9mm)

• Higher pressure load with increased velocity
• Heavier grain weight for strong performance
• Known for pushing performance on the higher end of the spectrum

That said—this is important:

• +P+ ammo is not rated for all firearms
• It can increase wear and recoil
• You should confirm your firearm can safely handle it before carrying

This is a more advanced choice—but when used appropriately, it’s a strong performer.

Should You Carry +P Ammo?

+P ammo runs higher pressure.

Pros:

• Higher velocity
• Can improve expansion

Cons:

• Increased recoil
• More wear on the firearm

If your firearm is rated for it, it’s a solid option—but not required.

How Often Should You Replace Carry Ammo?

• Every 6–12 months
• Immediately if exposed excessive moisture or water
• Replace rounds that have been repeatedly chambered

You should also test your carry ammo at the range to confirm reliability.

Final Takeaway

Keep it simple:

• Carry JHP defensive ammo
• Use reputable, duty-proven brands
• Avoid FMJ, reloads, and gimmicks
• Test your ammo in your firearm

Your goal is straightforward:

Stop the threat efficiently while minimizing unnecessary risk and liability.

FAQS

Can I carry FMJ if that’s all I have?

Yes—but only as a temporary solution. FMJ will work, but it is not ideal for self-defense due to overpenetration and reduced stopping effectiveness. Upgrade to quality defensive ammo as soon as possible.

Does ammo choice matter legally?

Yes. It can absolutely matter. Carrying standard, widely accepted defensive ammo (like law enforcement-grade JHP) is much easier to justify than using exotic or heavily marketed rounds.

Should I carry the same ammo that I train with?

No. You should train with FMJ because it’s more affordable, but carry JHP defensive ammo.

You should still test your carry ammo—run a few magazines through your firearm to confirm reliability.

Can I mix different types of ammo in my magazine?

No. Stick with one consistent defensive load.

Mixing ammo types (different bullet designs or grain weights) can create inconsistent recoil, point of impact shifts, and potential reliability issues.

How often should I rotate or replace my carry ammo?

Every 6–12 months, or sooner if it’s been exposed to sweat, moisture, or repeated chambering.

Carry ammo takes a beating—don’t ignore it.

Do I need +P or +P+ ammo for self-defense?

No—you don’t need it. Standard pressure defensive ammo performs very well.

+P or +P+ can offer increased velocity, but it also comes with more recoil and wear on your firearm. Only use it if your firearm is rated for it and you’ve tested it.

Colorado Concealed Handgun Permit (CHP) Class

If you live in Colorado and are applying for or renewing a Concealed Handgun Permit (CHP), state law requires completion of a qualifying training course taught by a verified instructor. Our Colorado CHP classes meet current statutory requirements and include legal instruction, firearms safety, and required certification documentation.

Self-Defense Insurance

Even a lawful act of self-defense can trigger criminal investigations, civil lawsuits, and significant legal costs. Many CCW holders evaluate self-defense insurance or legal protection plans to help manage those risks—coverage varies by provider and state, so understanding the differences matters.
