I have fired wolf through several different glocks without issues. What type of feeding issues were you having ? You can usually diagnose the problem by what the feeding issue is. Since you said that your other ammo cycled fine, I wouldnt beleive the issue to be with your glock. It could be the ammo , we all have ran into bad batches of ammo before.
I have read that some firearms do not like steel cased ammunitions. Some manufacturers of firearms state that firing steel cased ammunition through their firearms will void the warranty. I have never experienced a malfunction while firing wolf, but I have not shot wolf in high volumes. There are some firearms that are finicky, Glock really is not suppose to be one of them though.
I hope that you get everything worked out.
