I am trying to find the best solution for locks for my 8 Glock collection, I have tried the trigger locks and they are too bulky and the cable lock are not much better when trying to pack them into an other case. I have seen a lock called the Visualock but I cant find anywhere to buy them, the other thing I have seen is a Magazine lock but again dont know where to buy them, the last option is ofcourse the glock locking system but I am not sure if that can be added to a pistol afterwards or not. Does anyone have any idea where I can buy such locks or other idea to make it easier to transport them locked?
