MODULAR EXPANSION: Modular design allows for easy expansion and customization of your storage space, accommodating additional pistols or accessories as needed. FIT MOST GUNS: Each gun slot is 1.5” wide, most of the large pistols with accessories will fit in this rack without any issues. At the same time, the sturdy lightweight polymer board has better support capacity, so you don't have to worry about the gun frame falling apart when the gun is full.
