Hello all, I have an XDm 3.8 in 40. Spent a little time at the range this morning, and after about an hour of shooting, I snagged my thumb on a pin that walked out directly above the magazine release. I've had this gun for about 3 years now, and am completely problem free until now. Does anyone know what exactly this pin does? And would it be safe to simply tap back in, or do I have to contact Springfield for warranty repair? Thanks in advance for your help.
