SHTF seems to be a no go topic but this is directly firearm related so maybe it wont get closed.
Modified Sub2000(hipoint metal sight,foregrip,230lumen light,33rd glock magazines). I have worked up a 1600fps 124gr load for this gun using a slow powder.
S&W M&P9c
I am urban and carrying a rifle around here would draw tons of attention so I must have a compact rifle and the sub 2000 fits in a laptop bag.
