The Springfield Armory XD-M Elite 4.5" Tactical OSP packs all the advanced features of the Elite line into an operations-ready 9mm powerhouse. Sporting an extended, threaded barrel, an ability to accept today's top red dot optics, suppressor-height iron sights, the Match Enhanced Trigger Assembly (META), ambidextrous slide stop, improved slide serrations and an increased magazine of 22+1 (working in concert with a removable extended and flared magwell), the XD-M Elite 4.5" Tactical OSP offers the pinnacle of performance.
