sorry if this has been posted before, i just got it. i called springfield on it. they said this has occurred on all models, just most prominently the .40 for some unknown reason. this is only caused by an extreme amount of dry fires as in doing dry fire exercises very regularly over a long time frame. they are not selling/distributing a replacement part to be pro-active saying the average user should not wear this part out. they will replace it IF the part fails though. and of course they recommended using snap caps to do dry fire drills and the only time the pistol should be dry fired is to disassemble.
