Consider the size of firearms: There are significant differences in the sizes of different types of firearms. For example, the lengths and heights of long - guns and handguns vary. It is necessary to ensure that the length, width, and height inside the safe can accommodate the firearms. Especially for long - guns, their overall length should be taken into account to avoid the situation where they cannot be properly stored due to insufficient space.

Suitable installation locations: Determine the placement location of the safe, such as corners in the room, closets, etc. At the same time, pay attention to the space size of the installation location to ensure that the safe can be placed smoothly. Generally speaking, the depth of a safe usually does not exceed 20 cm. If you choose an in - wall gun safe, you also need to consider factors such as the thickness of the wall. In the wall, due to the limitation of the wall thickness, the safety of the structure usually does not exceed 200 mm.

In terms of performance.

Anti-theft performance

Bolt structure: A wing-shaped lock design is preferred. This design can enhance the anti-theft ability of the safe, making the connection between the door and the cabinet more secure and less likely to be pried open.

Steel plate thickness and material: The thickness of the steel plate should be no less than 10 mm, and it is better to be made of a single piece of steel plate. Meanwhile, the box body should be formed by one - time stamping, so that there are almost no gaps on the four sides, which can effectively prevent thieves from using tools to damage the safe.

Lock selection: You can consider combining mechanical locks with electronic locks. Electronic locks have multiple functions and high security, but there may be situations where they cannot be opened due to electronic failures; mechanical locks are relatively stable. Locks with complex structures should be preferred to improve anti - theft performance.

Weight reference: Safes of the same model have similar weights. If a safe is too heavy, it may be filled with other substances; if it is too light, the steel plate may not be thick enough. However, weight is not the only criterion for judgment, and other factors also need to be considered comprehensively.

Fire resistance performance

If you need to protect firearms in situations such as fires, you can choose a fireproof safe. Fireproof safes are generally made of various materials such as fire - resistant materials and high - strength materials, which can ensure that firearms are protected to a large extent in the event of a fire.

Waterproof performance

For some areas prone to rainfall and waterlogging, waterproof performance is a factor that needs to be considered. Waterproof safes mainly feature an underwater sealing design to ensure that the firearms inside the cabinet are not damaged by waterlogging immersion.

Functional features

Alarm function: Confirm whether the safe has an automatic alarm function and understand the activation conditions. For example, when the safe is opened abnormally or vibrated, it can promptly sound an alarm to alert the user or people in the vicinity.

Intelligent management: Some firearm safes are equipped with intelligent management functions, such as a networked alarm system. Once an abnormal situation occurs, such as illegal opening or movement, the system will immediately send an alarm message to the designated monitoring center or mobile phone APP to ensure that countermeasures are taken immediately. There is also a built - in in - position detection function that can monitor the status of firearms in real - time. Once it is found that a firearm is out of position, the system will automatically trigger an alarm to avoid potential safety hazards caused by negligence.

Other factors

After-sales service: Choose a brand that offers good after-sales service to ensure there are professional technicians for repairs. During the usage process, various problems may occur with the safe. Timely after-sales service can guarantee that the problems are properly resolved.

Certification mark: Check whether the product has relevant certifications such as the CCC certification mark. This is a guarantee of the product's quality and safety.

Appearance and workmanship: Observe the appearance and workmanship, including the connection of door gaps, the polishing of the cabinet, etc. Exquisite workmanship can not only enhance the overall aesthetics of the safe, but also reflect the quality of the product to a certain extent.

Anticorrosion treatment: Consider the anticorrosion treatment of the safe to ensure the integrity of its appearance and function. Especially for safes used for long - term firearm storage, anticorrosion treatment can extend their service life.

Brand Selection: Choose products from manufacturers with a good reputation and strong brand strength. For example, Deli offers high cost - effectiveness and is suitable for novice users; Tiger is a professional and powerful brand with a high recommendation index.
