g19 gen4 test fire date 2/24/2012. started with about 60 rounds of speer lawman 124gr fmj, then assorted ammo (winchester white box, federal champion and tulammo). ejector and recoil spring are the newer parts.
first time at the range today and started getting ejections to the head and to my left about half hour into my session, and seemed to get worse towards the end of the hour. a few of the casings to the head actually left black powder marks on my forehead.
at the time it didn't really bother me, and it still doesn't for the most part. but i'll probably try the tips from nowlin on my extractor to see if that helps any. other than the ejection problem, the g19 gen4 performed flawlessly.
