Yes it does include irons, I also couldn't find specifics on what sights they are but read several reviews that say they are included and they are nice

Yes, this includes a set of iron sights. I can't find anywhere what brand they are, not even on sig saur website but definitely come with adjustable flip up iron sights. Hope this helps.
