Actually Speer 125gr +P SJSP. The administration wanted to avoid the "nasty" image of HP bullets. Also the thinking at the time also felt that since our primary duties involved interactions with vehicles, the SJSP would penetrate vehicle sheet metal and glass better than JHP's of that time. When we transitioned over to the M681's we kept the same ammo.
We didn't finally get HP's until we transitioned over to the Beretta 96's. By that time all semi-auto defensive ammo was accepted to be JHP and the administration had to finally accept them. Unfortunately LE ammunition research & development (post 1986 FBI Miami shootout) was still in it's infancy and we wound up with low bid JHP ammunition that was ultimately found to be the cause of multiple failures to fire and failure to feed issues (among other issues) with some of the Beretta 96's.
