I have carried a Glock 19 as my duty weapon for about 7 years. mine is a two pin, serial # BLS7xx. It's unmodified and has the 5.5# connector. I experience failures to eject with Winchester Ranger 147Gn SXT and RA9T, and Speer 147Gn GDHP. The extracted round is caught between the Brl Hood and breech face, like a stove pipe, only the casing is horizontal. I have tried a new factory recoil spring, and brand new LEO mags. The slide has been detail stripped and cleaned. The extractor is not chipped or broken. Malfunction rate has remained unchanged, about 2 - 4%. The pistol never malfunctions with USGI M882 NATO 124Gn BALL. My other glocks; 17, 21, 23, & 26 NEVER malfunction. I would appreciate your recommendations. Changing ammo is not an option. my agency issues RA9T.
