Right now I carry .40 cal Speer GDHP 165 gr in my duty weapon and my concealed weapon. In my wife's 9mm I have 124 gr Starfire.
I know a lot of guys don't like starfire, but I know of 3 shootings with the .40 180gr, 2 were one shot stops. Saw the bullet on one of them, hit the guy in his chest through a coat/shirt and did not exit his back. The expansion was pretty wicked looking...... Other was a neck shot DRT, the other a leg shot, tore a pretty go hole........
Someone (Aphalghost?) I think said something about pratice. We all have our favorites, but getting the bullet into the target is the crucial first step that has to occour before all the bullet expansion, wound path, and penetration take place. I don't care what you miss me with, just don't shoot me!!
