Does Size Matter? How the TASER Pulse 2 Performs Against Larger Threats

Size doesn’t determine whether the TASER Pulse 2 works — physiology does. The device delivers a neuromuscular incapacitation response that overrides voluntary muscle control regardless of an attacker’s height, weight, or strength. A 250-pound attacker’s muscles respond to the same electrical signal a 150-pound attacker’s do. What matters more is shot placement and probe spread, not the size of the person on the receiving end.

Introduction

My neighbor Carol asked me something last spring that I think about a lot: “If someone twice my size came at me, would this thing even work?” She’d just bought a stun gun for her nightly walks, and that fear — the fear that her only line of defense might not be enough — was keeping her up at night. I understood it completely. When you’re a 5’4″ woman thinking about self-defense, the size gap feels like the whole story.

It isn’t. And I want to walk you through why, because this question deserves more than a reassuring pat on the back. It deserves real answers — the kind that let you sleep at night knowing you understand exactly what you’re carrying and why it works.

Does the TASER Pulse 2 work on bigger, stronger attackers?

Yes — because it doesn’t rely on pain or force to work. The TASER Pulse 2 uses neuromuscular incapacitation (NMI), which sends an electrical signal that hijacks the communication between the brain and the muscles. It doesn’t matter if those muscles belong to someone who benches 300 pounds. The signal disrupts the nerve pathway itself, not the muscle’s strength.

This is the part that brought Carol real comfort once she understood it. A punch depends on the size and strength of the person throwing it. NMI doesn’t. It’s closer to how a circuit breaker works — it doesn’t matter how big your house is, the breaker trips the same way every time. Her attacker’s size stopped being the scary variable once she saw it that way.

I’ve talked with women in their 60s and 70s who carry the Pulse 2 specifically because they know a physical altercation isn’t a fair fight to begin with. This isn’t about matching strength. It’s about having a tool that doesn’t need to.

What actually determines whether a stun gun stops an attacker?

Probe spread and connection matter far more than size does. When the two probes make contact with the body — ideally with some distance between them — the electrical current has to travel between them, passing through muscle tissue and disrupting it along the way. A wider spread across bigger muscle groups (like the torso or upper leg) tends to create more effective incapacitation than a narrow spread on a smaller area.

This is actually where a larger attacker can work in your favor. More surface area means more room for that probe spread to land across major muscle groups. It sounds counterintuitive, but a bigger frame doesn’t mean a more resistant target — it just means a bigger canvas for the current to do its work.

Clothing thickness plays a role too. Heavy winter coats can reduce effectiveness slightly by increasing the distance the probes travel to reach skin. That’s true for anyone, regardless of their size. It’s why aiming for exposed areas or lower-torso shots through thinner clothing layers tends to be part of what people are taught in basic training videos that come with these devices.

If you want the deeper research behind this — actual field data and testing on how these devices perform against larger and stronger attackers — this breakdown of the research is worth your time.

How is the Pulse 2 different from smaller stun guns when it comes to bigger attackers?

The Pulse 2 was designed with distance and duration in mind, both of which matter more when you’re facing someone with a longer reach or more raw strength. Its probes deploy several feet, meaning you don’t need to be within arm’s reach to use it — a real gift if the person you’re up against outweighs you by a hundred pounds.

It also delivers a set cycle of incapacitation once it connects, which gives you something a contact stun gun can’t: time. Time to create distance. Time to get to your car. Time to get somewhere safe. That built-in window is the whole point — it’s not about winning a fight, it’s about ending the encounter before it becomes one.

Compare that to a smaller contact stun gun, which absolutely has its place, but requires you to be close enough to touch your attacker. Against someone significantly larger, that proximity is exactly what you don’t want. Size matters less in terms of whether the device works — but it matters a lot in terms of which device makes sense for your situation.

Why do people assume size determines whether self-defense tools work?

Because we’ve been taught to think about self-defense the way we think about a fight — bigger, stronger, faster wins. That instinct is deeply human, and honestly, it’s kept people cautious in smart ways for generations. But it’s the wrong lens for electrical incapacitation devices, and clinging to it can talk people out of protecting themselves at all.

I think about my mother, who is 5’2″ and was convinced for years that “nothing would work” against someone bigger than her. That belief didn’t come from evidence — it came from fear dressed up as logic. Once she understood that NMI works on nerve signals rather than brute force, something shifted in her. She started walking to her mailbox at dusk again. She stopped avoiding the parking garage near her apartment. That’s what understanding how these tools actually work can give someone back — not just safety, but freedom.

This is why I care so much about explaining the “why” behind these products, not just selling the “what.” Fear of an unfair fight shouldn’t be the reason someone stops living their life the way they want to.

What else affects how well a stun gun performs, besides the attacker’s size?

Your own preparation matters more than almost anything else. Knowing how to draw the device quickly, how to aim for center mass, and practicing the motion beforehand changes everything. A device sitting untouched at the bottom of a purse doesn’t help anyone, regardless of who’s on the other end of it.

Environmental awareness plays a role too. Pairing a stun gun with something like a home security camera for your property, or a loud personal alarm for situations where drawing attention is your best first move, builds layers of protection that don’t rely on any single tool doing all the work.

And confidence itself changes outcomes. Attackers, research consistently shows, look for hesitation and vulnerability. Someone who moves decisively — even with a compact device like the Pulse 2 — often de-escalates a situation before it even requires firing, simply because they no longer look like an easy target.

Frequently Asked Questions About the TASER Pulse 2 and Larger Attackers

Can the TASER Pulse 2 stop someone much bigger than me?

Yes. The Pulse 2 uses neuromuscular incapacitation, which interrupts nerve signals to the muscles rather than relying on pain or force. This means it works the same way regardless of an attacker’s size, weight, or strength, because it targets the nervous system, not physical resistance.

Does body size affect how well a stun gun works?

Not significantly. What matters more is probe spread, muscle mass targeted, and clothing thickness. A larger body actually offers more surface area for probes to connect with major muscle groups, which can support effective incapacitation rather than hinder it.

How far away can I use the TASER Pulse 2?

The Pulse 2 deploys probes from a distance of several feet, which lets you create space between yourself and an attacker before deploying. This distance is especially valuable when facing someone larger or stronger, since it removes the need for close contact.

Will heavy clothing stop the Pulse 2 from working?

Thick clothing like winter coats can reduce effectiveness slightly by increasing the distance probes must travel to reach skin, but it doesn’t make the device ineffective. Aiming for the lower torso or areas with thinner clothing improves results in cold-weather situations.

Is a stun gun a fair fight against a much stronger attacker?

It’s not meant to be a fair fight — it’s meant to remove strength from the equation entirely. Because NMI disrupts nerve communication rather than relying on pain tolerance or physical force, it levels a playing field that would otherwise favor size and strength.

Should I practice using my stun gun before I actually need it?

Yes, absolutely. Practicing the draw, grip, and aiming motion builds muscle memory so you can react quickly under stress. A device you’re unfamiliar with, even a highly effective one, is less useful in the moment than one you’ve practiced with a few times.

What’s the difference between the Pulse 2 and a smaller contact stun gun for bigger threats?

The Pulse 2 deploys probes from a distance, letting you create space before an attacker reaches you. Smaller contact stun guns require direct touch, which means closing the gap with someone larger or stronger — a riskier position if you have a choice to avoid it.

Does the Pulse 2 need multiple uses to stop a bigger attacker?

Typically no. A proper probe connection delivers a full incapacitation cycle regardless of the attacker’s size. The goal isn’t repeated use — it’s using that initial window of incapacitation to create distance and get to safety.

Conclusion

Carol still walks her neighborhood every evening. She still carries her Pulse 2 clipped where she can reach it in a heartbeat, and she still feels the occasional flicker of “what if.” But that fear doesn’t run her life anymore, because she understands something now that she didn’t before: her safety was never actually about matching someone else’s strength. It was about having a tool that made strength irrelevant.

That’s what I want for you too — not a false sense of invincibility, but real, grounded understanding of how these tools work and why they work for you, regardless of who you might be up against.
