took a minute but is great now

Put this on my 19x Gen 4 with alpha wolf threaded barrel. At first had nothing but failure to feed or stove pipes. Couldn't figure it out, then after 5 or 6 tear downs, I think it was not exactly aligned with the frame. This is minorly different than the slide. Once properly aligned works great. Also older or weak mag springs don't help. New mag springs and now she's a monster.
