*Semi-Auto pistol locks engage the extractor, locking the slide onto the   frame. *(Please note: Locking the slide to the frame is a secondary benefit that doesn't apply to all gun models) Whether the slide is locked or not, the internal gunlock primarily functions to securely lock the chamber, preventing a round from chambering, and ending accidental discharge.

  • If your gun is stolen, it cannot be used against you
  • Locks do not interfere with handling and or holstering
  • locks eject like empty brass - fast access
  • Gun friendly - all materials used are softer than ammo brass
  • Whether the gunlock is engaged (locked) or not, a round cannot be chambered without racking the slide first - ENDING ACCIDENTAL DISCHARGE
