Johnathan Martin, from Arizona (how could you guess?) sends his Aircraft Inspection & Documentation carry. From Every day Carry.
In addition to the S&W M&P 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.
