I carry a Glock 23, with 2 extra mags, a Nitecore MT2A light, and the Schrade SCHF15 knife.
My G23 sits in a Renaissance Firearms “Boxer” OWB rig, my extra mags sit in the “Chihuahua” mag holders, and my light sits in a custom build, all made by www.renaissancefirearms.com
My Schrade sits in the kydex sheath that came with it.
I carry the Glock 23 for reliability, comfort, and capacity, in this holster for solid retention, quick access (shall I ever need it), and light weight comfort.
