look like glasers to me?
I don’t think Glaser makes 5.7 ammo.
It originally came with SS190 ammo for armor-piercing capability.
They the sissies got squeamish, so there’s a lead-core round.
I think there’s a third “training” round.
Blue on ammo means “training”, so it might be the cheap training round in the pic.
That round was designed to penetrate bullet resistant vests originially, but when then civilian version of the P-90 was offered for sale in the US they developed a non-AP round.
It’s for all intents and purposes a 22 magnum in terms of power. Its good that he didnt have a more powerful gun, more people might have died.
As far as Im aware, Glaser doesnt offer a 5.7 cal loading.
