Yep, on body 99.9% of the time, along with 2 spare mags. These are back ups to the back ups. I know I’m still in the honeymoon phase with the Upscale 2, and haven’t even loaded up the MC 1.0 yet, but I just happened to grab a ranger green Upscale 2 from Primary Arms in the last few minutes of their sale a few days ago for $42. Packs and bags that I like have a habit of getting discontinued. Not taking any chances with this one!
