Johnathan Martin, from Arizona (how could you guess?) sends his Aircraft Inspection &amp Documentation carry.  From Every day Carry.

In addition to the S&ampW M&ampP 9c in an Alien Gear Shape Shifter four. appendix carry holster.

He complements that with a Benchmade Bugout Blade, a Streamlight Stylus Pro and a Secrid wallet.  Oh yeah, and a Skilcraft aviator pen.
