As of this fall, this is my cool weather EDC. I have started wearing an unlined cotton canvas jacket when it's too warm for a real jacket, just so I can carry this rig.
Sig Fastback Carry in .45.
I like the extreme cant on that holster because I can move the pistol farther back and still be able to draw easily. And then a gust of wind won't expose my rig. And while driving, the pistol is not blocked by the seat belt and is easy to draw.
You might notice that the mags are loaded to capacity-1. I found that in IDPA competition, I would often fail to seat the mag fully on a tactical reload, and then it would drop out when I fired a shot. Leaving one round out makes it much easier to seat the mag. It also is easier on the springs.
That is a Leatherman Wingman that I sometime wear inside my belt. If I wear it outside it tends to work it's way off. And the light is an UltraFire with a 14500 li-ion battery that I generally carry in my pocket. It also likes to work itself off my belt.
