57 x 28 or 9mm?

I'm on the fence and am trying to consolidate ammo for when shtf. I just got the Smith and Wesson M&P 57 (no safety, of course) and its out performing my S&M MP 9c on penetration and accuracy...but the ammo is super expensive.....plus its not a common round. I'm wondering if I should stick with the 9mm for those two reasons? side note: the green tip 57x28's penetrate class 2 body armor and they will put a serious hurting on class 3.

9mm because it's available and cheap so you can train more.

The chances of being assaulted by people in body armor is near zero outside of ZOG jackboots, and you would need a rifle and comms to survive that.

The real debate is 5.56 NATO or .308 Winchester for a main rifle, and if everyone should have a long-range rifle with optics.

You should have rifles for different mission capabilities, I would put CQB and one long range marksman rifle with optics as a basic setup. Then sidearms, body armor and harness and related kit, comms, etc. Ideally everyone would spring for NODs and related gear but that shit is so expensive.

That's why I have two 5.56 for personnel work under 100 yards and an AR10 in .308 for dealing with vehicles, armor, or 200-400 yards.

I'm a bit late to the conversation, but I have the same philosophy. I've got 5.56 for my main gun, for generic protection/missions/general use. It's cheap, fast, low recoil, accurate, etc. The AR10 would stay at home base or be used for select missions. Base protection vs personnel protection. Specific use vs general use.

Oh Shit! I gotta pick one and run! I'd take the 5.56. With my 9mm as well.

I have a C308 that also shoots 7.62 x 51. I just got the X-91 50 round drum mag for it and a bi-pod. So I have that squared away. I have a Savage Axis 308 with a scope as well..both are zeroed in and ready to roll... I have an AR-15 and I also bought a Panzer AR-12 shotgun with a 20 round drum mag. ..and of course I have my body armor from when I was in the Marine Corps, I recently updated the plate and bought trauma pads for it... I was debating dropping the 9mm and getting a FN P-90 and the accompanying pistol that both shoot 57x28...but after all the feedback it looks like that would be a serious judgment error.

The consensus seems to point to a 16" 5.56mm all-rounder, long-range .308, and a .300 BLK SBR. Urban and forest environments may change that, and so would fielding in rural areas, where a longer-range bolt action would be perfect.

5.7 is only great with AP ammo, and 9mm is widely available. Id say get both if you can and branch off later depending on what you feel most comfortable with later.
