I purchased this to transport my duty/everyday carry weapon for an upcoming trip. The exterior is solid, but still pliable. I would not run this over with a vehicle, as you might with other Pelican cases. The interior is filled with foam, both pluckable and non-pluckable. It is a fairly simple task to customize the pluckable foam to the shape of whatever it is you are stashing inside - although, admittedly, the final product does not look as polished as a true custom mold. There was sufficient room in this case for a partially disassembled Glock 19, a 50-count box of 9mm rounds, a Glock 19 magazine, a Glock 17 magazine and a very small box cutter. (. see pic.) (The holster will NOT fit in the case, with everything else.)The exterior slots are woefully small and inadequate for anything but a TSA-style luggage lock, so I drilled/fabricated my own solution. (. again, see pic.) I had no reservations about drilling into the case, as it is definitely sturdy enough to handle a strategically placed hole and a seriously heavy duty lock. At this point, I am very pleased this purchase. I will report back after my trip.
