Just went to the range to fire our brand new Glock 17 Gen 4. It has the most updated RSA and ejector (called Glock about it). Test fire date was 07-12-12 In the first three magazines, I had a total of three stovepipes. Pictures are below. I did not clean it before shooting. I'm wondering what to do about this. Glock is adamant that it's the current RSA and Ejector. Could it be a magazine problem? It was a new 10 round mag that came with the gun. If I can recall correctly, at least two of the jams occurred on the last round of the mag. Should I clean it and re-shoot? Was going to sell it, but don't want to pawn off those problems on somebody else. I'm aware that limp-wristing can be an issue, but within a couple minutes I shot my Gen 4 21 and had no problems at all. Does anybody have any suggestions as to what I should do? Thanks for your help!
