I sent my G17 Gen4 to Glock because I was getting hit in the face with the spent casings. One even went down my wife's shirt and left a burn mark. But anyway it took them about 2 weeks to repair. The ejector was replaced with the new style one, number 30274 and they did fire it cause I sent it to them cleaned and could tell it was fired. They were really nice and helpful over then phone, like always. Went to the range about two weeks ago with no problems, even with one of my friends that has never shot before, casing were flying to the right like it should.
