I've used a variety of ammo in .40 over time now. I've put everything through from a rare 125 gr which is no
longer on the market to the 135 gr Federal hollow points; MagSafe frangible; 165 and 180 fmj and JHP. Everything but
the 155 gr.
ALL are good. IMO you pays your money and takes your choice. I know CCI isn't going to bring back the 125 gr, but
I really did like that one for the low recoil.
