Rethinking 9mm

[m4fun]

Conceptionally for a SHTF scenario, having extra possibilities if .223 runs dry, but then I like have an upper in all calibers -

Practicality aside, it is fun in FA - and suppressed!

9mm AR SBR is fun to have and with a Can attached it is a blast.
For SHTF I don´t think so, have to much other stuff that is better suited for the job.

If you own a 9mm UZI and a 9mm pistol, a 9mm Colt AR also makes sense. Modified UZI mags work well in both the UZI and the Colt AR resulting in commonality of ammo and mags.
