stack-on pc-900


Stack-On claims this device “Meets TSA Airline Guidelines.” According to TSA Guidelines for Transporting Firearms and Ammunition, firearms may be transported in “a locked hard sided container.” The guidelines do not say how resistant to unauthorized access the container must be, aside from stating, “Locked cases that can be easily opened will not be accepted.” The phrase “can be easily opened” is the only language in the guidelines that might be construed to address unauthorized access. Since the TSA does not endorse products, responsibility is left to manufacturers to decide whether their products are TSA compliant.

Stack-On PC-1690

This is one of the most common portable cases made in China for export. Its basic design has remained unchanged for at least a decade. Given the security issues built into this device, I would not recommend its use under any circumstances.

Stack-On PS-514-12


This is one of the most common safe designs manufactured in China for export. The basic solenoid-locked mechanism inside is used in thousands of Chinese-made safes. Even the keypad fitting is installed on products made by multiple manufacturers, including Bolice Machinery & Equipment Suzhou Co., Ltd., Mexgrand (Suzhou) Metal Products Factory, Wujiang Granden Electronic Mechanical Co., Ltd., Yangzhou Super Industry Co., Ltd., and others. Put simply, this Stack-On safe is as generic as a product can possibly be.

Stack-On PS-1514

This is an updated version of an earlier model, the PS-514-12. Components of the solenoid-locked mechanism inside the PS-1514 have been redesigned to prevent “bouncing” the safe open. The redesign also includes shielding for the solenoid, making the new safe much more resistant to tampering should an attacker try to insert wires through the door.
