I purchased a new 5” Prodigy that was inoperable out of the box. After a very frustrating couple hundred rounds of varying factory FMJ ammo it was clear that it wasn’t a “break in” period and needed to go back to Springfield. Got a return label, sent it in and got it back about a month later. I was told that the feed ramp and disconnector were polished and that the barrel was refit. They obviously did some work to it as the slide wouldn’t hang up on the disconnector and it did seem to cycle better the first magazine with only three failure to feeds from a 17 round mag. Again tried different ammo and magazines with no improvement. After about a hundred rounds it jammed up just short of chambering and the slide would not move. A RSO and I worked on freeing it for about ten minutes and he finally was able to eject the round. Like an idiot I decided to give it one more chance and had the same malfunction two rounds later, with the slide locked up tight, round almost chambered and no ability to engage the safety. I have no faith that this pistol can be fixed at this point (300 total rounds fired) and I don’t really want to throw money and parts at the most problematic and honestly unsafe gun that I’ve ever owned. I own Springfield rifles and have never had any problems whatsoever. This thing is a disaster.
