blowed it up after 3 rounds? I do believe I'd be sending that one back.
It would cost me more in shipping than the factory replacement part I already ordered. If there are still issues after the parts swap then I’ll let Glock work their magic. I honestly believe that ejector was out of spec. I’ve compared it to a G20, G21SF, G40, G41 and all their ejectors are flush with the rear polymer housing and this one is slightly elevated. Could have been a problem with the housing or the metal ejector but the new part replaces both so hopefully, fingers crossed, it should be taken care of.
