If you’re a gun owner who values both safety and responsibility, chances are you already know that storing firearms unsecured is a risk no one should take. But here’s the thing: even a high-quality gun case won’t do much good if it’s not locked properly—and if you’re a retailer or distributor of gun cases, that’s a key point to emphasize to your customers, because it directly ties to the gear you sell. Over the years, I’ve worked with hundreds of gun owners who walked into my store (let’s call us a trusted gun case supplier, no names, no links) thinking a $50 hard-sided case was enough protection, only to realize they’d skipped the critical step of securing the case itself inside a home safe. It’s a mistake that leads to avoidable accidents, theft, and legal headaches—and today, I’m breaking down exactly how to do it right, based on what we’ve learned from both product testing and customer feedback. Gun Case
First, let’s address why this step matters so much. A gun case is designed to transport or store a firearm, but a home safe is a dedicated security space. Locking the case inside the safe adds two layers of protection: one against anyone who might access the safe, and another against someone who could get into the case if the safe were compromised (it’s a long shot, but why take it?). For casual gun owners, locking the case alone might feel sufficient, but for anyone with kids, roommates, or guests who aren’t fully vetted, that extra layer is non-negotiable. For our part, we’ve seen customers come back saying they “forgot” to lock the case inside their safe—and it’s always the ones who regret it later. So let’s start with prep work, because you can’t just grab a lock and start attaching things.
Before you even pick up a lock, you need to make sure your gun case fits properly in your safe, and that there’s enough space to secure it without damaging either the case or the safe. Here’s a quick prep checklist we share with every customer: Measure both the interior dimensions of your safe (height, width, depth) and your gun case, leaving at least 2 to 3 inches of clearance on all sides. That gap isn’t just for air circulation (which prevents moisture buildup—another big one for gun care) ; it’s also what makes it possible to thread a lock through the case and the safe without forcing things. If your safe is too small for your case, you might need to downsize the case or upgrade the safe, but that’s a separate conversation. For most standard 3- to 5-gun hard-sided cases, a mid-sized home safe (1.5 to 3 cubic feet) is more than enough.
Next, choose the right type of lock. This is where a lot of people go wrong: they grab a small combination lock they use for a gym locker, which is way too easy to cut with bolt cutters. At our store, we only recommend two types of locks for securing a gun case inside a safe: a heavy-duty cable lock with a reinforced steel core, or a padlock with a hardened steel shackle. Let’s break both down. Cable locks are great because they’re flexible—you can thread them through the gun case’s carrying handle holes, through the trigger guard of an unloaded gun (with the chamber open, obviously), and then wrap them around a fixed metal bar inside the safe. The best cable locks have a vinyl coating to prevent scratching your case’s finish, and a diameter of at least 7/16 of an inch—anything smaller is too easy to snap. Padlocks should have a shackle made of boron carbide or hardened steel, not cheap brass, and a key or combination that’s not something your kids could guess. We always tell customers to avoid combination padlocks if they’re worried about someone watching them enter the code; a keyed padlock with a deadbolt shackle is more secure, as long as you keep the key in a secure spot (not taped to the safe, obviously).
Now, let’s get to the actual process of locking the gun case inside a safe, step by step. I’ve tested this with dozens of different case and safe combinations, so this is a method that works: First, make sure your gun is unloaded, the chamber is open, and the case’s internal locks are engaged (if it has any). You’d be surprised how many people skip this basic safety step just because they’re focused on locking the case. Next, place the case inside the safe, making sure it’s not pressing against the safe’s door or any electronic components (like a keypad or lock mechanism) — you don’t want the case to get in the way when you close the safe. Then, grab your lock of choice. If you’re using a cable lock: thread one end of the cable through a reinforced hole in the gun case (most quality cases have these on the side or back, not just the flimsy carrying handle) and through the trigger guard of your unloaded, open-chambered gun. Pull the cable tight so the case can’t shift, then wrap the other end of the cable around a fixed metal object in the safe—like a gun mount bracket, a bolt that’s been embedded into the safe’s wall, or a heavy-duty shelf support. Make sure the cable is wrapped tight enough that it can’t be pulled away, then secure the cable’s lock end to the rest of the cable. If you’re using a padlock: Thread the padlock’s shackle through two points: a reinforced hole on the gun case, and a corresponding hole on a fixed part of the safe. Some safes have pre-drilled holes specifically for this purpose, but if yours doesn’t, use a metal bar or a bracket that’s welded to the interior—never try to thread the shackle through plastic or thin metal, which can break or stretch. Once the shackle is through both points, close the padlock. And before you shut the safe door, double-check that the case is locked securely: give it a gentle tug to make sure it can’t slide away, and that the lock’s shackle or cable isn’t loose. If it moves at all, adjust it and try again.
Wait a second—what if your gun case doesn’t have reinforced holes? That’s a common question we get, especially from people who own cheaper, no-name cases. Here’s the thing: if your case doesn’t have reinforced, metal-lined holes for locking, you shouldn’t be using it to store firearms long-term. That’s why we only sell gun cases with at least two steel-reinforced locking points on the side—cheap cases with plastic holes can crack or tear when you add the pressure of a lock and cable, defeating the whole purpose. If you already have a case without reinforced holes, you can upgrade it by adding a small steel eyelet through the plastic or fabric, but that’s a temporary fix at best. Our advice to customers who come to us with that issue is simple: invest in a quality case that’s built for storage and security, not just transport.
Another point to consider: safe compatibility. Not all gun safes are the same, and some work better for this method than others. A small, key-locked pistol safe might not have enough interior space or fixed metal points to secure a full gun case, while a larger, cabinet-style safe with interior shelves and mounting points is ideal. We always recommend that customers measure their safe before buying a case, and vice versa—if you’re a retailer or supplier like us, that’s a key piece of advice to pass along, because it prevents returns and helps customers make a better choice. Also, make sure your safe is anchored to the floor or wall if it’s large enough—even a locked case inside a safe can be stolen if the safe itself is light enough to carry away. That’s a separate security step, but it’s worth mentioning because it ties into how you secure your case.
Now, let’s talk about common mistakes people make when locking a gun case in a safe. The first one is using a flimsy lock—like a thin combination lock or a cable smaller than 7/16 inch. We’ve tested cutting those with bolt cutters in our warehouse, and it takes less than 10 seconds. The second mistake is skipping the safety check: leaving a loaded gun in the case, or not closing the case’s own locks before putting it in the safe. The third is not leaving enough clearance around the case, which can damage the case or the safe over time, or make it hard to access the lock later. The fourth mistake is using the case’s carrying handle as the only locking point—we’ve seen a dozen cases where the handle pulled right off when someone tried to thread a cable through it, because it’s not designed for that kind of pressure. That’s why we always emphasize using the side locking points on our cases, which are reinforced to handle that stress.
As a gun case supplier, we also get asked about accessories that make this process easier. We sell a line of heavy-duty cable locks that we’ve tested with our cases, and they have a vinyl coating to prevent scratching, so you don’t have to worry about ruining your case’s finish. We also offer small steel eyelets for customers who need to add locking points to older cases, and even gun mounts that fit inside most safes, which make it easy to both mount the gun and lock the case around it. All of these accessories are designed to work seamlessly with our cases, so if you’re buying from us, you don’t have to guess what will fit.
It’s also important to touch on legal responsibilities, because that’s a big part of why this step matters. In many places, gun owners are required by law to store firearms securely to prevent unauthorized access. If a child gains access to an unsecured gun, or if a firearm is stolen from an unprotected case inside a non-locked safe, you could face legal consequences. Locking your case inside a safe isn’t just a good security practice—it’s often a legal one, depending on where you live. That’s another reason we make sure to include this information in every product manual we send out with our cases.
Let’s wrap this up with a quick recap to make sure you don’t miss anything. The process is simple, but it’s not a step to skip: 1) Prep by measuring your case and safe, making sure there’s enough clearance. 2) Choose a heavy-duty lock (reinforced cable or hardened padlock). 3) Thread the lock through your case’s reinforced locking points and a fixed metal object in the safe. 4) Tighten the lock so the case can’t shift, and double-check before closing the safe. 5) Avoid common mistakes like flimsy locks, weak points, and skipped safety checks.
