(Elm City, NC, 2006)In addition to my own research and what my students bring into the Concealed Handgun Carry class every week, this guide was reviewed by Massad Ayoob of Massad Ayoob Group, whose opinion appears below. [Keep only if true — Chris: I handled the product(s) on this page myself. Details are in the test record at the end.] The method line at the end of the article says exactly how this guide was built.
Weight is one of the first things I ask about on any small gun box, and it surprises students. They want to talk about fingerprint readers. I want to know whether a burglar can tuck the box under one arm and open it later at his own kitchen table. A light box that isn’t bolted down is just a carrying case with a lock on it.
The Langger Biometric Slider Gun Safe answers that question better than most boxes its size. Langger lists 12.4 pounds of 16-gauge carbon steel in a narrow upright box that mounts on a wall or furniture, or stands on the floor. You get in with a fingerprint, a PIN or a key, and the handgun comes out of a drawer instead of from under a lid.
My verdict: a sturdy, fixed-spot box for one handgun up to 9.5 inches long plus a spare magazine. It sits in the $100 to $200 band, so you’re paying for steel and weight, not for a fire rating or a roomy inside.
FYI, prices and ratings are accurate as of time of writing.

Langger Biometric Slider Gun Safe – Best Heavy-Duty Upright Biometric Safe Under $200
HIGHLIGHT:
A 12.4-pound, 16-gauge steel slider that mounts from the top, left or right, or stands upright on the floor.
TOP PANEL & FINGERPRINT READER:
The controls are on the top edge: four numbered buttons in a row with a round fingerprint reader just below them. In the photos you can see that layout plainly, and another shot shows the buttons lit blue with a green ring around the reader on a box mounted beside a nightstand. Mounted upright next to the bed, that top edge is where your hand lands.
Langger says something on this listing I wish more sellers would: if your fingerprints are rough, worn or dry, the reader may struggle, and that’s why the PIN is there. Carpenters, farmers, mechanics and folks who wash dishes all day often have prints that read one day and not the next. Enroll more than one finger, and test the reader in the morning, at night and right after you wash your hands. If it misses, you want to learn that now.
PIN, LOCKOUT & KEY:
The PIN is your second way in. Langger also lists a lockout: after three wrong tries, the safe beeps and stops taking the PIN. That’s good against a child punching buttons. It’s bad if it’s you, in the dark, with your hands shaking. The listing doesn’t say how long the lockout lasts or how it resets, so get that from the manual before you count on this box in an emergency. Everybody who’s supposed to have access should know the code cold, and it shouldn’t be a birthday, an address or anything a kid could guess.
There’s a silent mode for the beeps. In a shared bedroom I’d use it, but check the manual on whether the wrong-code warning still sounds with the sound off.
The manual key is the last way in, and it works no matter what the electronics are doing. I tell every class the key doesn’t go in the drawer under the safe, and it never goes where a child can find it. Your key ring or a second locked spot. Make sure it turns the day the safe arrives, not the night you need it.
THE SLIDE-OUT DRAWER:
This is a slider, so the handgun comes out of a drawer below the keypad instead of from under a flip-up lid. In the photos you can see the drawer open on a box mounted to a wall by a door, and on another box between a bed and a nightstand with the keypad lit and a pistol grip showing.
An upright drawer feels different from a flat box. Think about where the grip ends up when it opens, and mount the safe so your shooting hand gets there without crossing your body or fishing around. Then practice it the way I teach a draw: lights off, from lying down, until it’s smooth every time.
INSIDE ROOM:
Langger says it holds a handgun up to 9.5 inches long plus one spare magazine, and that the inside is lined with thick, dense foam so nothing slides around. No inside measurements are listed. With the outside only 3.5 inches wide, plan on one handgun of fairly standard shape. If your pistol wears a light, an optic or a long slide, measure it and ask the seller before you order.
In the photos you can see the drawer open on the foam cradle, a pistol sitting in it seen from above, and a box mounted on its side with a pistol lying in the open drawer. If you want a second handgun in there, this is the wrong box.
One odd number: the spec sheet lists “capacity” as 5.67 kg. That’s a weight figure, not a gun count, so don’t use it to judge fit. The 9.5-inch figure is the one that matters.
BUILD & STEEL:
Langger lists 16-gauge carbon steel with a corrosion-resistant finish and a weight of 12.4 pounds (the seller’s text rounds it to 12.5 and calls it the heaviest of its kind, which I can’t check). Remember gauge numbers run backward: 16-gauge is thinner than the 14-gauge some other boxes list. Much of the weight here comes from the size of the box, not a thicker wall.
The bullets mention anti-theft protection with an anti-impact latch, but the listing text cuts off and the details aren’t spelled out. There’s no pry rating, no bolt count and no fire rating. As an old lawman, I’d call it a theft-deterrent and child-access box, not a vault. The weight helps. The screws holding it down help more.
POWER:
The listing doesn’t name the battery type, the battery life or any outside power option. For a fingerprint and keypad safe, that’s a real gap. Find the battery type in the manual, learn how the low-battery warning works, and check whether you can change batteries without taking the safe off the wall. Then put a reminder on your phone to swap them on a schedule. The key is your insurance, so keep it where you can reach it.
MOUNTING:
This box gives you more mounting choices than most. Langger says it installs from the top, left or right onto a flat surface with the included screws, or stands upright on the floor. In the photos you can see it on a wall in a corner beside a wooden cabinet, mounted on its side in the gap beside a mattress, on the side of a small end table with the keypad lit, and tucked down low beside a bed.
Screws are the only hardware listed, so look at what they’re made for. A stud, a solid wood panel or a thick piece of furniture will hold. Drywall alone won’t, and a 12-pound box with a gun in it will pull out of a flat-pack shelf. The listing also suggests a vehicle. If you go that way, check your state’s rules for a gun in a car first.
If you have children in the house, this part isn’t optional. North Carolina’s safe-storage law (G.S. 14-315.1) can put you in court if a child gets hold of a loaded gun you left within reach and something happens with it. Other states have their own versions.
WHAT TO CHECK BEFORE YOU BUY:
Where it earns its keep: The Langger Biometric Slider Gun Safe is sturdy with a smooth-sliding door, programs easily, has a fingerprint reader that generally works well, and stores up to 20 fingerprints for multiple users.
Where it falls short: The fingerprint sensor can be inconsistent, needing a precise, slow touch or dropping registered prints after a few days. Instructions sometimes do not match the exact unit received, and some units arrive defective.
Who it’s for: Fast bedside access to one pistol for someone willing to re-register fingerprints as needed. Not for anyone who needs fully dependable biometric access under stress every time.
WHAT TO WATCH:
The unknowns add up: no inside measurements, no battery type, and no word on how long the PIN lockout lasts. The seller promises round-the-clock customer service through the order or by email. Treat that as a promise until you’ve seen it kept. And once it’s screwed to the wall, this is not a box you carry from room to room.
WHO SHOULD BUY IT:
Buy it if you keep one handgun in a fixed spot by the bed, under a desk or in a closet, you want three ways in with a PIN backup for hard-to-read prints, and you like the heft of real steel. Skip it if you need a box to carry between home and car, want room for two guns, or need a fire rating. It also costs more than the basic boxes, so make sure the extra steel is what you’re paying for.

Langger Biometric Slider Gun Safe FAQ
What size handgun fits the Langger Biometric Slider?
Langger says a handgun up to 9.5 inches long plus one spare magazine. No inside measurements are listed, and the outside is only 3.5 inches wide, so measure your gun with any light or optic on before you order.
What batteries does the Langger slider use?
The listing doesn’t name the battery type or life, and it doesn’t mention an outside power port. Check the manual, change batteries on a schedule, and keep the backup key where you can reach it.
How can I mount the Langger safe?
The seller says it installs from the top, left or right side onto a flat surface with the included screws, or stands upright on the floor. Go into studs or solid wood. Drywall alone won’t hold a 12-pound box.
What if the fingerprint reader won’t read my print?
Use the PIN or the key. Langger notes that rough fingerprints can be hard to read, which is why the PIN is there. After three wrong PIN tries it beeps and blocks PIN entry, and the listing doesn’t say for how long.
Is the Langger slider fire rated?
No fire rating or certification appears in the listing. It’s a black carbon steel box sold with screws, so keep papers you can’t replace in a separate rated container.
