THE IMAGE ABOVE IS A PAID ADVERTISEMENT

Have new Glock 34 Target. Noticed after 200 rounds that there is a powder streak down 50% of the case from end of case to rim. Shooting Speer Lawman 115 grain. Also get a case to jam in eject port about every 30 rounds, using 10 round magazines(Calif law). Cant remember if the streaking was present during the first 200 or so rounds. Is tis normal? Need ssome help if possible. Thanks anyone

That generally happens with light loads. That would explain the other problem as well. Try different ammo. That gun should function perfectly from the box.
