RPNB RP311F Review: Slim Bedside Safe, Is It Worth It?
The RPNB RP311F is a slim, vertical, under-the-furniture handgun safe with a fingerprint reader, a keypad and a backup key. It suits someone who wants a bedside or desk-side box that takes up almost no floor or drawer space and who is comfortable with a small interior. It is a poor match if you want a wide, cushioned drawer-style safe, a clearly documented fire rating, or a battery setup that is spelled out in detail on the page.
Bottom line:
- Good fit: a narrow mount-it-and-forget-it bedside safe with three ways in (fingerprint, code, key), listed at the time of writing in the under $100 range.
- Watch out: the listing gives outside dimensions only, no interior size, and no battery details in the data we reviewed.
- Before buying: confirm your handgun fits a slim cavity and check the current price on Amazon.
This review is based on the Amazon listing, the seller bullets, the spec sheet and the way the product is positioned against similar safes. We have not handled this unit, so where the listing is silent we say what to verify rather than guess. If you are still comparing options, our guide to the best biometric gun safes and the broader best gun safes roundup show where it sits.

Access and lock
The RP311F offers three routes in. The primary one is a fingerprint reader. The seller describes a 500 DPI semiconductor sensor and says matching takes less than a second. That is a seller claim, so treat it as a design target rather than a guarantee. Capacitive and semiconductor readers generally work best with clean, dry fingers and enrolled prints captured from several angles, so plan to spend a few minutes enrolling each finger you want to use, and re-enroll if your skin changes seasonally.
The second route is an electronic combination, which the spec sheet lists alongside the biometric lock. This is your fallback when a finger is wet, cut or gloved. The third is the physical key included in the box. Because the key sits outside the electronics, it is the access method that still works if the reader misbehaves or the power source is depleted. How you store that key matters: a key left in a nightstand drawer defeats the point of a locked box, and a key kept too far away defeats the point of a quick-access box. Many households keep it on a separate person-carried ring or in a different locked location.
Programming is fairly approachable according to the brand’s own walkthrough. If you want to see the enrollment process before buying, the brand channel has one.
Watch: the manufacturer’s own channel, RPNB SAFE, shows how to program this model.
Build and security features
The spec sheet lists alloy steel, and the seller bullets describe a steel body with a black, corrosion-resistant finish. The listing does not give a steel gauge, a bolt count or a pry-resistance rating, so there is nothing here to compare against, say, a 14-gauge competitor. Slim vertical safes in this class are generally built for casual-access protection: keeping a firearm away from children, houseguests and a quick smash-and-grab, rather than defeating a determined attacker with tools and time.
A second point worth knowing: the long product description on the page mixes in text that looks like it comes from the brand store and other products, including phrases about fire resistance, a touch screen, an auto-open lid and a state certification. None of that appears in this model’s spec table, and the data we have does not confirm any of it for the RP311F. Please do not buy this safe expecting a fire rating or a state-approval listing unless the seller confirms it for this exact model. If your state or your insurer cares about certification, check your state’s requirements directly; laws vary by state, so check yours.
Security-minded buyers also like to see how a product fares under scrutiny. A third-party channel has published a video about this model that, by its title, shows it being opened with a simple tool. We cannot vouch for the method or whether it applies to current units, but it is a useful reminder to watch independent material, not only the brand’s.
Watch: the Handgun Safe channel covers how this model can be opened.
Interior and fit
The outside measures 1.8 inches deep by 7.43 inches wide and 13.47 inches tall. With walls, a door and the lock hardware to account for, the usable interior has to be considerably smaller than that, and the listing does not publish interior measurements. A cavity this narrow generally accommodates a slim handgun standing on its side or lying flat in a vertical slot, not an optic-equipped full-size pistol, a weapon light, or a spare magazine stacked beside it. We would not assume anything beyond one compact or slim handgun.
The “capacity” field says 8 pounds, which is unusual: that reads like a load figure rather than a count of firearms. We would not treat it as a promise about what fits. Measure your handgun at its widest point, including any grip texture, light or red dot, then compare against the interior dimensions the seller can confirm. If the page does not state them, ask through the Amazon Q&A before ordering.
Mounting and placement
This is where the RP311F earns its place. The thin profile is meant to disappear under a desk, beside a nightstand, on a shelf or against a vertical surface. The seller says it can be mounted from the right, left or top side, and the spec sheet calls it an under counter mount. That flexibility lets you pick which way the door swings, which matters if you sleep on a particular side of the bed.
Mounting hardware is not itemized in the data we have, and the included-components field lists only the key. Check the listing and the box for screws and any template so you are not making a hardware-store run. A safe that is merely sitting on a shelf can be carried off, so fasten it into something solid: a stud, a thick board or furniture frame that will bear weight. Particleboard is the weak link in many desks and nightstands, so a through-bolt with a backing plate is more reassuring than a short wood screw.
Power and batteries
The data we reviewed does not name the battery type, expected battery life, or whether the unit offers an external power port. That is a real gap for an electronic lock. Before buying, check the listing and the manual for the battery type, how a low-battery warning behaves, and where to find the replacement cells. Plan on replacing batteries on a schedule instead of waiting for a warning, and keep the physical key reachable for the day you forget.
The safe’s backup key is the redundancy here. Because the key bypasses the electronics, the practical risk is not being locked out forever; it is being locked out at a bad moment while the key is elsewhere. Rehearse all three methods when you first set it up, and again every few months.
What owners say
The data we have for this listing does not include a summary of owner feedback, so we will not paraphrase themes we cannot see. What we can say is that the listing is among the most-reviewed safes in this category on Amazon, which makes it easy to read plenty of buyer experiences yourself. When you do, filter for the most recent comments and look for patterns rather than individual stories: fingerprint reading consistency, how long the batteries last, how easy the mounting hardware is to use, and whether the interior size matched the description. Consistent complaints on any of those points are worth more than a single dramatic one.
The seller bullets invite buyers to get in touch with questions or difficulties, but they do not describe warranty terms, so look for those on the listing before you rely on any promise.
Pros and cons
Pros
- Very slim 1.8-inch profile that fits places most safes cannot.
- Three access methods: fingerprint, electronic combination and key.
- Mountable from the right, left or top side.
- Listed in the under $100 range at the time of writing.
- Light enough at 7.7 pounds to handle during installation.
Cons
- Interior dimensions are not published, and the narrow body suggests room for one slim handgun only.
- No battery type or life information in the listing data.
- No steel gauge, fire rating or certification confirmed for this model.
- Mounting hardware is not itemized.
How it compares
The BILLCONCH Biometric Handgun Safe goes the other direction: a flat, low-profile box with a published interior size, a phone app and a long list of enrollable fingerprints, but it wants a shelf or drawer rather than a wall or underside. If you want a drawer-style layout, that is the better shape.
The ONNAIS Iron Pro is a small wall-mount unit that pairs a fingerprint reader and a keypad with a backup key and an emergency USB-C power option, which answers the battery question more directly than the RP311F listing does. It is worth a look if power backup is your top concern.
The Hornady RAPiD Safe Night Guard uses RFID entry with a wristband and key fob, adds a clock and USB ports, and is described as 14-gauge steel with a security cable. The Hornady RAPiD Safe Keypad Vault is a larger bolt-down box with RFID, a code and a key. Both cost more or vary in price compared with the RPNB, but they publish more about construction.

Fingerprint reliability and the recall question
Biometric safes get extra scrutiny, and rightly. Read our explainer on whether biometric gun safes are reliable and our biometric gun safe recall guide before you buy any fingerprint model. For storage and fast access, also see our picks for the best quick access gun safes. As with every safe, a locked box is only one part of safe storage: laws vary by state about child access and storage, so check yours.
Price and deals
At the time of writing, the RPNB RP311F sat in the under $100 range. Prices on Amazon move often, so check the current price before you decide. We keep a separate page on the RPNB RP311F promo code situation, which covers clip coupons and sale seasons, without promising any code. You can also check today’s price on Amazon.
Final verdict
The RP311F is a smart pick if the main problem is space: a bedside or desk-side location where a drawer safe will not fit, and where one slim handgun is all you need to secure. Three access methods and flexible mounting are the strengths. The gaps are the missing interior measurements, the missing battery details and the unconfirmed construction specs, plus the stray certification language in the product description, so verify those before you buy. If you want a roomier or better-documented box, one of the alternatives above is a safer bet; if you want to see it for yourself, view the RP311F on Amazon.
RPNB RP311F FAQ
Will my handgun fit in the RPNB RP311F?
The listing gives the outside size, 1.8 by 7.43 by 13.47 inches, but not the interior. Because the body is so slim, expect room for one compact or slim handgun at most. Measure yours, including any light or optic, and ask the seller for interior dimensions before ordering.
What batteries does the RPNB RP311F use?
The listing data we reviewed does not name the battery type or life. Check the product page and manual before buying, replace batteries on a schedule instead of waiting for a warning, and keep the included key reachable as your backup if the electronics fail.
How can I mount the RPNB RP311F?
The spec sheet lists an under counter mount, and the seller says it can be mounted from the right, left or top side. Hardware is not itemized, so check the box contents, and fasten it into solid material instead of thin particleboard.
What is the backup if the fingerprint reader fails?
It has an electronic combination and a physical key. The code covers wet or gloved fingers, and the key does not depend on power. Store the key away from the safe, and practice all three methods after setup.
Does the RPNB RP311F come in different variants?
No variants are listed in the data we reviewed, only the RP311F model. Product descriptions on the page mention features such as fire resistance and certification that are not in this model’s spec table, so confirm anything important with the seller first.
