Here's how you replace one and see number 2 on how you can check the pin's condition.
The XD striker retainer pin is the small roll pin you see in the hole in the top of your slide, just forward of your rear sight. This pin holds the striker in place, and is an item that will periodically break and need to be replaced. A new pin only costs a dollar or so, and you can replace it yourself by following these instructions. It probably makes sense to keep a few of these pins on hand.
REMOVAL OF OLD/BROKEN PIN
Disassemble slide, per these instructions:
Use a 3/32nd roll pin punch, and tap old retainer pin out from the BOTTOM of the slide UPWARD toward top of slide. The retainer pin hole is tapered on the bottom side, so don't tap it out toward the bottom.
REPLACEMENT OF NEW PIN
Get a new pin .
Place some masking tape on top of your slide around the retainer pin hole to protect the finish while you work.
Squeeze or "crimp" one end of the retainer pin just enough to get it started. Some have had to crimp the pin until the edges were touching.
Drive the pin in from the top of slide, either using a regular hammer or mallet alone, or a cupped punch. If you just tap it in with the hammer alone, there's less risk of marring the slide.
Once retainer pin is nearly flush with slide, use a drift punch to seat the pin just below the surface of the slide.

If you want to pick up a reinforced set of 3 for $12 it's worth it .
