My SHTF/TEOTWAWKI rifle would be one of my FAL clones, probably my R1.
My reasoning is I have spare parts kits to keep them running for quite awhile, plus they'll reach out and touch someone with power to spare. I bought my fair share of surplus ammo back when it was plentiful and cheap along with a quite a few magazines.
That rifle is accurate and utterly reliable.
Sidearm would be a Colt Double Eagle .45acp
Knife has to be my ScrapYard Regulator.
