Gooooood morning dear Glock friends! Yesterday I went to the range with my G19 gen4. She has the RSA marked "0 - 4", and I used Fiocchi ammo (124 grains). Yesterday were her second 100 ammo pack shooted in her life. OK. After the first mag the pistol is open, I release the mag, I insert onother one mag, I push the hold open button and... incredible! The cartridge stay blocked in the zone of the ramp of the barrel... I solve the problem and with a lot of angry words I shoot some more. After 10 minutes another FTF! And after shooting some more ammo the third FTF of the day! I went home very very very depressed. I had never seen this problem with the previous 100 ammo pack. I return home, I try for half an hour to insert magazines, releqase them, release the slide with the hold open button, manually, strongly enough and... no problems at home... May be that at the range I have used too sweety manner with the inserting of the magazines? Or one of the two magazines ( 15 rounds ) , numbered with a strange number 6, is a little problematic? Or the ammo?... I don't know, but I'm in love with my Glock and I don't want to hate her... SORRY FOR MY FPSrussia LANGUAGE! Greetings from Italy! - UPDATE - : 6/7/2012 - - - NOW THE PISTOL IS OK: new ejector 30274, new RSA 0-4-3, and she works well, no brass in face, no ftf, no fte! I know that some people can't resolve the problem until the new extractor but in my story it's no more a neverendingstory!! go U S A and thankyou to all of you for your helps!
