Glocks owners manuals say not to shoot reloads. It doesnt specify lead or jacketed.
Kind of funny that you quote the manual when you clearly don't care what it says given that you're shooting reloads in your Glock.
Glock doesn't make a secret of the prohibition on "unjacketed" bullets. I don't know why they don't put it in the owner's manuals, but it is thoroughly covered in the armorers course and in other Glock publications and informational materials.
