Hello, Lovemyglock, and Welcome to the Forum!
If you post a *Hi there* in Introductions, other Members will have a chance to say Hi right back.
About your question, like others had said, Glocks prefer jacketted ammunition (what Shooter said, plus BEB and Plated bullets). Using unjacketted (bare lead) bullets will void the warranty on your Glock, and lead to cladding of the bore, which is a serious safety issue.
Cheers!
