Excuse me, but, that simply isn't true!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.
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.Blasphemy!! You speak heresy!
