I'm still working through my stock of Remington Golden Sabre believe it or not.
The replacement, after I'm sure that my gun likes it 100%, will be Critical Defense. One, it was designed for the average guy where Duty was built to pass the FBI protocols of shooting through car doors, glass etc. That to me is over penitration that i don't need. Secondly, I understand that when you go to court the ammo you used will be brought up in court and possibly used against you. Thus the fact that my ammo's name is Critical Defense can't hurt. It doesn't show prementitation.
As far as bullet performance goes, I'm sure all those other brands' magic self defense bullets look great in their tests. Further I'm sure those manufactures know what they're doing. But I think in the real world any those magic bullets will work if you hit your target where you should.
Finally, if ball ammo has been so effective in .45ACP all these years, then how is the difference between brand Y and brand X JHP going to make a difference?
