I have two P-07's, a standard black one from 2017, and a OD Green from 2018. I like them both. I swap them out between range/dryfire duty and carry duty every six months or so. It also lets me tinker around with one, to test new CGW parts or whatever, while keeping the other one operational.
Since they both came with two mags, I have four P-07 mags. I carry one in the gun and a second one in the mag pouch. I occasionally dump the carry ammo out of them at the range, to test them, but they don't see a lot of action. A third one is an empty spare in case one of those has issues and needs to be swapped out. A fourth one I keep empty with a mag block (also prevents slide lockback) and orange tape on the base just for dry fire drills.
Then I have two P-10 C magazines that I use and abuse at the range regularly. I got a better deal on them than what P-07 mags were selling for at the time.
Then I just ordered two new P-07 mags with +2 adapters. I'm thinking I'll load 34 rounds into those and carry them in a dual mag carrier occasionally.
