Some of the stock ones hold up well, others don't. Dry firing can damage the stock pin. In my P-09, the pin showed signs of peening. In my P-07, the stock pin looked fine but I replaced it anyway and kept the stock one for a spare.
If your stock pin looked undamaged, it should be fine until you can get a replacement. Just make sure you installed it with the split in the pin facing up (12 o'clock) when you are holding the gun in the shooting position.
Did your stock pin have any visible damage?
