Rails on Springfield XD accessories

[Solidux]

Noticed the holster/mag pouch/speedloaders all have rails on them. Anyone know their intended purposes besides this?

The speed loader snaps onto the side of the magazine pouch. That's it intended purpose.

Or, you can mount your laser to the magazine pouch and put the speed loader on the gun. It will confuse the bad guy.

Is that a high cap bayonet? It's to make carrying all the accessories easier.
