Will it fit my gun?
Guard II uses a universal trigger-guard design that fits most modern firearms, including pistols, rifles, shotguns, and BB guns. A single unit secures one firearm at a time.
Fit varies by trigger-guard geometry — contact us if your model isn’t listed.
Can I trust fingerprint recognition in extreme conditions?
The cheap misreads people complain about come from optical sensors — the kind that take a picture of your fingerprint. Guard II uses a 360° capacitive sensor that reads the electrical pattern of the ridges of your skin from any angle and matches in approx. 0.1 seconds. The sensor employs live-finger detection, and its algorithm updates your stored print every time you use it, with environmental compensation — so a paper cut or a season of dry skin doesn’t lock you out.
Validated performance:
- Dry, calloused fingers: adaptive sensitivity adjustment maintains 99%+ accuracy
- Cold temperatures: functional down to −22°F
- Hot temperatures: functional up to +149°F
We spent years of engineering making sure your Guard II is as reliable in extreme conditions — when you need it the most.
Do I need to remove the lock manually after unlocking?
No. The moment your fingerprint registers, the auto-eject mechanism releases the lock and pushes the two halves off the trigger guard automatically — nothing to unscrew, unthread, or put down.
The auto-eject makes unlocking and drawing one seamless motion when speed matters. No lid to open, no box to reach into.
Does it work in the dark / in a purse?
Yes. The capacitive sensor doesn’t need light to read a fingerprint — your firearm is ready in complete darkness by instinct alone, or unlock it discreetly in your purse so you’re prepared for any situation.
What happens if the battery completely dies?
You’re not locked out. The lock warns you at 15% capacity — weeks before depletion — and the mechanical backup key opens it with no battery and no fingerprint, independent of power.
I’m left-handed — will it work for me?
Yes. Guard II’s mount is reversible — you can lock the fingerprint-reader half to either side of your firearm, so it works left- or right-handed.
The recommended setup: position the fingerprint-reader half on the side of your draw hand, so unlocking and drawing are one seamless motion.
What happens if someone tries to force it open?
Guard II’s body is built from reinforced steel and zinc alloy to withstand abuse — it has gone through rigorous testing in extreme conditions, including smashing, pulling, and picking.
Any unauthorized unlock attempt also triggers a loud alarm and a red strobe light — enough to scare the person away, or to let you know what’s happening.
Can my kids open it by guessing?
There’s nothing to guess. With traditional locks, kids usually find the combination by peeking or guessing. Guard II has no code and no key on the daily path — access is fingerprint only, and a fingerprint that isn’t enrolled doesn’t open the lock, period. No amount of peeking or guessing will give your kids access.
What if I’m not happy with it?
We offer a 30-day satisfaction guarantee from the ship date. Every unit also carries a 1-year warranty against defects in materials and workmanship.
We’ve invested years in engineering and testing the Guard II, and we stand behind it completely. We’re confident that once you experience biometric security, you won’t go back to traditional locks.

Unlocking and drawing is one seamless motion
The draw is the unlock. Your finger touches the sensor as your hand closes, and approx. 0.1 seconds later the lock is off and auto-eject clears the trigger guard.
-
01Grip and touch the sensor
The sensor sits exactly where your trigger finger already rests, so the way you pick the gun up is already the way you unlock it. Nothing to press and nothing to aim at.
-
02Unlock and eject
The sensor reads your fingerprint and auto-eject pushes both halves off the trigger guard in one move. Nothing slides, nothing has to be pulled back.
-
03Draw
The gun comes up free of the lock in the same motion you were already making. No pause between unlocked and aimed.
Compatible with most modern firearms, works with left and right hand
One universal trigger-guard design fits pistols, rifles and shotguns. The mount is reversible, so the reader half sits on your draw side — left or right.

Why our customers love their Guard II
Drag the cards
-

I've seen a lot of locks claim they can't be broken. This is the first one I tried to break and couldn't.
-

My truck sits in the sun all day. Two summers with the lock in the console and it still reads my fingerprint on the first try.
-

Rode all morning, hands full of dust and sweat. It opened on the first press, same as always.
-

Every other lock I've owned assumed a right-handed draw. This is the first one that works on my side.
-

Grabbed it off the nightstand at 3 a.m. without turning on a light. It was already open by the time I had a grip on it.
-

I've charged it twice since spring. That's the whole maintenance routine.

10 months
Battery
One charge lasts about 10 months, or ~1,000 unlocks. It warns you at 15% — weeks before it dies — and a full charge on USB-C takes about 2 hours.

2 keys
USB & Mechanical Backup Keys
Two keys, two jobs. The mechanical key opens the lock with no battery and no fingerprint — that's your way out of a dead battery. The USB admin key handles enrolment and system resets.

Loud
Unauthorized & Child access
No code to guess, no key to find — a fingerprint that isn't enrolled doesn't open it, and failed attempts set off a loud alarm.

Do I need to remove the lock manually after unlocking?
No. The moment your fingerprint registers, the auto-eject mechanism releases the lock and pushes the two halves off the trigger guard automatically — nothing to unscrew, unthread, or put down.
The auto-eject makes unlocking and drawing one seamless motion when speed matters. No lid to open, no box to reach into.
How many people can open it?
Guard II Pro stores up to 20 fingerprints — enough for every adult in the house, or for different fingers under different conditions.
Adding a print requires the admin fingerprint or the USB admin key, so nobody can enroll themselves. And of course, a fingerprint that isn’t enrolled doesn’t open it.
I’m left-handed — will it work for me?
Yes. Guard II Pro’s mount is reversible — you can lock the fingerprint-reader half to either side of your firearm, so it works left- or right-handed.
The recommended setup: position the fingerprint-reader half on the side of your draw hand, so unlocking and drawing are one seamless motion.
How long does the battery last?
About 10 months per charge — or about 1,000 unlocks. The lock warns you at 15% battery, weeks before depletion, with a built-in alarm so you always know when to charge. A full charge takes about 2 hours on USB-C.
Does it stay locked without power?
Yes. The locked state is fully mechanical — no power is needed to stay secure.
What happens if the battery completely dies?
You’re not locked out. The lock warns you at 15% capacity — weeks before depletion — and the mechanical backup key opens it with no battery and no fingerprint, independent of power.
Does it work in the dark / in a purse?
Yes. The capacitive sensor doesn’t need light to read a fingerprint — your firearm is ready in complete darkness by instinct alone, or unlock it discreetly in your purse so you’re prepared for any situation.
What happens if someone tries to force it open?
Guard II Pro’s body is built from reinforced steel and zinc alloy to withstand abuse. Guard II Pro has been accepted by the California Department of Justice as an Approved Firearm Safety Device — it has gone through rigorous testing in extreme conditions, including smashing, pulling, and picking.
Any unauthorized unlock attempt also triggers a loud alarm and a red strobe light — enough to scare the person away, or to let you know what’s happening.
Can my kids open it by guessing?
There’s nothing to guess. With traditional locks, kids usually find the combination by peeking or guessing. Guard II Pro has no code and no key on the daily path — access is fingerprint only, and a fingerprint that isn’t enrolled doesn’t open the lock, period. No amount of peeking or guessing will give your kids access.
Is this a safe?
No — Guard II Pro is not a safe, and it’s not trying to be. It doesn’t enclose or anchor the firearm, so it doesn’t replace a theft-resistant safe. What it does do: it makes the trigger inaccessible to anyone whose fingerprint isn’t enrolled.
Can it handle heat and cold — like in a truck?
Validated performance:
- Cold temperatures: functional down to −22°F
- Hot temperatures: functional up to +149°F
We spent years of engineering making sure your Guard II Pro is as reliable in extreme conditions — when you need it the most.
