Any five seven lovers or haters out there? I've had one for quite a few years now and have been very happy with it, I am looking to get an AR-5.7 since the P-90 is comically overpriced.
As a disclaimer I don't use it as a carry gun (who would...) I like it because its fun to shoot and the rounds are light, so you can carry 1000's of rounds without being immobile when the zombies come ;)
I just don't see the application for myself personally. Over the years I have decided to slim down my caliber diversity. By I guess narrowing it to only a few calibers I am better equipped and supplied in the ones I have.
I agree having less caliber diversity defiantly has its advantages, especially if we are talking about the zombie apocalypse or other SHTF scenarios.
