Like everyone else I regret not getting the Brownells D60 or at least 2x40 with a coupler.

I'm making a DMR featureless rig that mounts off a tripod so the extra length of the P40 is irrelevant.

If you had bought 1 or, 2 you would have regreted not having bought 3 or 4. Natural for people to think that.
Cost per round, weight, mobility, reliability, the 30 rd mags makes sense. You did good. A week ago, we didn't even have 30 rd mags. There will be other opportunities seeing as how the 9th and the SCOTUS are shaping up.

^^this. I had the same internal conversation as you.
