Hello, So I am new to the Glock world and recently did a polymer80 G17 build. However I am having a problem. I used a Lone Wolf Distributors Frame completion kit, Part # LWDSPECTREFULLS on Brownells website, and I am not sure I have the right ejector installed because every time I fire the weapon, the casing comes straight back and normally hits my left arm or hat. This kit came with 2 ejectors, one for the 9mm and one for the 40 S&W. Could someone please help me figure out which one I need to use in my gun. If you go to brownells page, the ejector I am currently using is the bottom one, which comes to more of a point. I included some photos to help people understand what I am talking about.
