If you are not recoil sensitive, use the Proload 180 Gold Dots. 1300 honest fps out of my 1006. Recoil is stiff but a Sprinco recoil reducer helps with that.
Civilian legal Winchester 175 gr silvertips clock about 1250 fps for a substantial wollop.
Sub sonics are for girls (and FBI Agents).

DO NOT SHOOT ANY UNJACKTED BULLETS THROUGH A GLOCK. Unless you have installed an aftermarket barrel. Glock barrels are not suitable for plain lead bullets.

Blasphemy!! You speak heresy!

How so? Dare I quote from the Glock owners manual? Shooting unjacketed ammo through a Glock barrel is flirting with disaster. You may get away with it for 100 rds and #101 MAY blow up your barrel. You may never have a problem. There is sufficient information to believe it is not advisable.
