Smith & Wesson® M&P® (full size) 9mm drop-in barrels

It's no secret that the key to great accuracy is good training. After that, it often comes down to a match-grade barrel. Built from high-quality stainless steel, precision polished, and treated with premium coatings, these barrels rival custom work and deliver the best in accuracy and performance, round after round. Threaded barrels and protectors use 1/2-28 threads for compatibility with after-market accessories like suppressors and compensators.

  • Match-grade precision drop-in barrel
  • 1:10 Twist / 6 groove rifling
  • CNC-machined from 416R stainless steel billet results in superior corrosion resistence and durability
  • Low-temperature vaccum PVD coating creates a durable barrier against wear and tear even in the harshest environments
  • BORSLICK™ Boron Nitride DCD (Dynamic Compound Deposition) inner bore treatment resists heat and carbon buildup
  • Target crowned muzzle
  • Individually hand inspected for accuracy
  • No gunsmith required
  • Limited lifetime warranty
