The box that I am looking at shows to be product number 53966, Lot AO3R32. I was able to get 2 cases of the stuff w/o selling any surplus body parts or commiting a felony. While it works just dandy in the single 1911 Commander platform that I have tested, the dang stuff flat refuses to play nice through a G 36. Mag springs were replaced, still no joy. Have any other Glock owners, especially 36 owners, had problems with this factory ammunition? Thanks, salty edit: The Speer factory JHP length is about .012-.015 shorter than its stable mate Federal. Maybe the Glock wants a longer length. Dunno. What do you think? ty sd.
