Yeah, they burn alot. I had one shoot back in between my eye protection!! You shouldve seen me trying to take them glasses off!. Anyway, i had to send my brand new G30sf to Glock and it took like a good three weeks. It will be worth the wait however cause my baby shootin sweet now. They shouldve emailed you directions on how to send the gun back. Repairs take like 2-4 weeks unless your getting slide refinishing; that adds extra two weeks. Good luck and keep us updated!
