I have a 5 year FN SLP MK1 bought it new and has had about 8000 rounds through it. Cleaning it today for a match next weekend. Reinstalling the slide and bolt and a part drops out. Seems the pin that hold the bolt slide and bolt slide link, broke. The remaining half stayed in place. The link is working properly, with the broken piece installed, under hand cycling. My ?, is that pin available as a replacement part, or is it new bolt slide time.
