This slimline case measures 16" x 12" x 3". This handgun size has the same construction features and internal locking system as do all our cases except this case is large enough for 2-3 handguns yet still has the added security of a side locking system and an airline strength cable that works in conjunction with the internal locking system. This case can be secured with the cable to luggage for travel or to another stationary object and to the floor of a vehicle with the optional mounting plates(Model #HGMP)or the Mounting Bracket(Model #12163MB)for more security.
