Need help with Glock mystery
I just went to the range with my new G17 3rd Gen. RTF2. I am shooting my own reloads. When I shoot the gun, all the brass is being ejected right into my face! It's like I am shooting a G.I. 1911. There was a guy there who shoots IPSC with a Glock and is an armorer, we tried everything. He had every part conceivable to trouble shoot this. We tried a different recoil spring, striker spring, extractor. He shot it with his ammo, no change. Why is this gun doing this?? This was the first trip to the range for this gun, just picked it up from the store yesterday. I did clean the gun prior to going to the range. Also put a storm lake barrel into it just to try everything. Only thing I haven't tried yet is factory ammo.
