Langger Biometric Slider Gun Safe Review: Worth the Price?
The Langger Biometric Slider Gun Safe is a heavy, upright, slide-open box with a fingerprint reader, a PIN keypad and a backup key. It makes sense for someone who wants a firmer, more substantial bedside or desk-side safe than the thin-sheet portable boxes, and who is happy to mount it on a wall or let it stand on the floor. It is a worse fit if you need to carry it between locations often, want a wide interior for several handguns, or expect a fire rating.
Bottom line:
- Best for: a fixed bedside, desk or closet spot where one handgun plus a spare magazine needs fingerprint, PIN or key access, in the $100 to $200 range at the time of writing.
- Trade-off: it is slim and tall, so the interior is narrow, and the data does not say what battery it uses.
- Before buying: check that your handgun is under the stated 9.5-inch length and confirm the current price on Amazon.
This review is based on the Amazon listing, the seller bullets and the specification table. We have not handled the product, and the data we reviewed contains no summary of owner feedback, so we have not guessed at what buyers say. Where the page is silent, we tell you what to verify. If you are weighing several types, our guide to the best biometric gun safes and the main best gun safes page give wider context.

Access and lock
There are three ways in. The fingerprint reader is the main one for quick access in the dark. The seller points out something honest and useful: if your fingerprints are rough, worn or dry, the reader may struggle, which is exactly why a PIN is included. People who work with their hands, climb, garden or wash dishes all day often have prints that read inconsistently, so enroll more than one finger and test the reader in the morning, at night and after washing your hands.
The digital PIN is the second route, and the seller describes it as the quick alternative for when a print will not read. It also has a lockout behavior: after three wrong attempts, the safe beeps and will not accept a PIN. The listing does not say how long the lockout lasts or how it resets, so find that in the manual before you rely on the safe in an emergency, and make sure everyone with access knows the code cold. Choose a code that is not a birthday, address or a sequence a child could guess.
The third route is the manual key, which the seller lists as a backup. It works regardless of the electronics, so it is your answer to a dead battery or a failed reader. Keep it somewhere you can reach but a curious child cannot, and not in the same drawer as the safe.
There is also a silent mode. The seller frames it as useful when you do not want to wake others or announce yourself at night. Being able to mute the beeps is handy in a shared bedroom, but confirm in the manual whether the wrong-code alarm still sounds when the sound is switched off.
Build and security features
The seller describes 16-gauge carbon steel with a durable, corrosion-resistant finish, and says it weighs about 12.5 pounds, calling it the heaviest of its kind. That last point is a marketing comparison we cannot verify, but the 12.4-pound figure on the specification sheet does make it a solid piece of kit for a handgun safe this size. Gauge numbers run opposite to thickness: 16-gauge is thinner than the 14-gauge steel some competitors advertise, so do not confuse weight with a thicker wall; the weight here comes partly from the box’s overall size.
The bullets also mention anti-theft protection with an anti-impact latch, but the listing text is truncated and the details are not spelled out. There is no pry-bar rating, no bolt count and no fire rating in the data. Think of it as a theft-deterrence and child-access box rather than a hardened vault. Laws on storage and child access vary by state, so check yours, and keep the code and key away from anyone who should not have them.
Interior and fit
The outside is only 3.5 inches wide, so the interior is narrow. The seller says it fits handguns up to 9.5 inches long, which would cover most handguns, and one spare magazine. The seller adds that the inside is lined with thick, dense foam so the contents do not slide around. The listing does not give interior measurements, so verify these before you order if you use a light, an optic or a long slide.
Because the safe is tall at 11.8 inches and the handgun stands or lies in a vertical orientation, accessibility depends on how it sits. A pistol in foam in an upright slider has a different feel from one in a flat drawer box, so think about how you will draw it. A narrow box with a firm foam cutout rewards a handgun that is already a fairly standard shape. If you carry a model with unusual width, or you want a second handgun, this is the wrong format.
The spec sheet lists “capacity” as 5.67 kg, which is a weight rating rather than a count. We would not treat it as a guarantee of what will fit. The handgun length and magazine figure from the seller is the more practical guide.
Mounting and placement
This is a flexible mounter. The seller says you can install it from the top, left or right side onto a flat surface with the included screws, or simply stand it upright on the floor. That makes it usable under a desk, on the back of a nightstand, inside a closet, on a wall or on a bookshelf, and the listing also suggests a vehicle, which is a case where you should check local rules and use the safe responsibly.
The included screws are the only hardware listed, so check what they are made for. Wall studs, a solid wood panel or a thick piece of furniture will hold; drywall alone will not. A 12-pound box with a handgun inside has more weight than a flat-pack shelf can hold, so choose a backing that will not shear.
If you travel with it, also remember that a mounted safe is not a portable one. Our guides to the best portable gun safes and best car gun safes cover boxes designed for moving around.
Power and batteries
The data does not name the battery type, expected battery life or any external power option. That is a notable omission for a fingerprint and keypad safe. Check the manual and the listing for the battery type, how a low-battery warning behaves and whether you can swap cells without unmounting the safe. Replace batteries on a regular schedule rather than waiting for the warning. The physical key is your protection, so confirm it works as soon as the safe arrives.
What owners say
We were not given a summary of owner feedback, so we will not invent themes. The listing is widely reviewed on Amazon, so there is plenty to read. Look at recent comments for how consistently the fingerprint reader works over months, how the PIN lockout feels in real use, whether the mounting screws and template are adequate, and whether the foam and internal fit match the description. Also check what buyers say about support: the seller promises round-the-clock customer service through the order or by email, but treat that as a claim and look for how it has worked for others.
Pros and cons
Pros
- Fingerprint, PIN and key access, with a PIN fallback for hard-to-read prints.
- 16-gauge carbon steel and about 12.4 pounds of weight per the listing.
- Mountable from the top, left or right, or upright on the floor.
- Dense foam lining described by the seller.
- Silent mode for night use.
Cons
- Narrow 3.5-inch body with no published interior measurements.
- Battery type and life not given.
- PIN lockout duration is not described.
- No fire rating or pry rating in the data, and sits in a higher price band than basic boxes.
How it compares
The Vaultek LifePod 20 is a polymer travel case with a backlit keypad and backup keys, a published interior of about 9.6 by 7.3 by 2.1 inches, and a removable tray. It suits a car or a trip better than a fixed bedside spot, and it has no fingerprint reader.
The Hornady RAPiD Safe RFID opens with a wristband, fob or sticker and also a key, with a spring-assist lid and 14-gauge steel. It is a faster, touch-free approach that suits a nightstand, but it is not biometric. The Hornady RAPiD Safe Keypad Vault adds a code and is meant to be bolted down.
The StopBox USA goes the opposite direction: a mechanical code lock with no batteries, a light plastic body and 81 settable combinations. If battery worries put you off, that is the answer, though it is a different style of box altogether.

Final verdict
The Langger is a reasonable choice for a household that wants a sturdy, wall-mounted or floor-standing box with three access routes, an honest PIN fallback and a silent mode. Its limits are the narrow interior, the unknown battery and the missing lockout details. If you want a wider interior, a travel case or a battery-free design, one of the alternatives will fit better; if it matches your handgun and your spot, view the Langger on Amazon.
Langger Biometric Slider Gun Safe FAQ
What size handgun fits the Langger Biometric Slider?
The seller says it fits a handgun up to 9.5 inches long plus one spare magazine. Interior measurements are not listed, so measure your handgun including any light or optic. The exterior is only 3.5 inches wide, so expect a narrow, single-gun layout.
What power or batteries does the Langger use?
The listing data we reviewed does not name the battery type or life, and it does not mention an external power port. Check the manual and listing, replace batteries on a schedule, and keep the backup key easy to reach.
How can I mount the Langger safe?
The seller says it installs from the top, left or right side of a flat surface with the included screws, or it can stand upright on the floor. Fasten into studs or solid wood, because drywall alone will not hold a 12-pound box.
What if the fingerprint reader will not read my print?
Use the PIN or the manual key. The seller notes rough fingerprints can be hard to read, and the PIN is the alternative. After three wrong PIN attempts it beeps and blocks PIN entry, but the listing does not say for how long.
Does it come in different variants?
No variants are listed in the data we reviewed. The listing shows a black carbon steel model with screws included. Confirm any details about fire resistance or certification with the seller, since none appear in the spec table.
