Don't have any pods i want to cut up right now. But this saturday i'll probably find one.
edit: yes, i do have a pod i want to cut up right now.
Didn't cut the groove as far as i'd like, but it's late so didn't use a dremel, just a box cutter and some sheet metal sheers. Pod walls are thin, so they flexed too much after the cut and the mag turned freely in it, which i didn't want. Wedged a small product manual in there, which proved to be the perfect filler. After seeing this for real, i dunno if it's a great idea on the field. It'd be hard to return mags to the pod housings since the groove has to line up. I wouldn't choose this over a mag pouch. And i'm sure glad i won't miss that pod.
