It's this one, in the 11.5" x 8.5" size, so roughly the size of a sheet of letter paper. It came with a few feet of aircraft cable, and I padlocked it to a metal ring in my trunk which was probably intended for securing cargo. It's actually rather roomy when holding my S&W Shield and spare mag; it'll hold something larger, no problem. There is also a larger size, in case you need to store your carry and your New York reload.

It's fine, good for the price. I wish the cable lug did a better job of staying in place in its little slot in the safe when the safe is open, but it's a minor issue.
