Great case with Pluck-n-Pull foam for custom fitting of stuff going inside. The foam is designed to be in a cubic shape when combined so you can lay down the pulled foam to adjust the depth of the interior to fit the thickness of the item. Measure and pull foams only as much as necessary, and in larger blocks instead of one by one, where possible. This will be perfect for carrying through the airport with TSA compliance. Or through communist states such as New Jersey, California, etc. where you might not be able to use your Concealed Carry Weapon permit. I put down a Smith and Wesson M and P Shield 9 with ease within minutes. I was able to fit the pistol with an extended magazine in it, extra two extended magazines side by side, a compact 50 round box of 9 mm and a compact speed loader between the magazines and the ammo box. No rattle, no bouncing. I had to lay down the pulled foam under the pistol and the ammo box. If Just Magazines, I could fit 6 to 8 extended magazines. For best fitment, I used Lock Master model 141Q padlocks. They came in pack of 4 locks with 2 keys that can open them all. Pelican 1170 takes two padlocks. The specs for that padlock is 1/4'' or 6 mm shackle, 7/8'' or 22 mm shackle hoop.
