I remember when we first got the NYPD issued G-19s in '91, they gave us politically correct FMJ, the JHP ammo was too barbaric. I think that ended when a couple of transit shooting with the bullets bouncing off the tiles in the subway platforms changed their minds. I think the 124 +P GD was a big improvement. I know 4 of them did fail to penetrate a Carhartt jacket in a Mid-town Manhattan shooting.
