Semi-Automatic 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- giving you fast access
      • Locks are gun-friendly; the 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

The lock is accompanied by a child resistant folding key, with a bushing that self-centers the key to the lock.

      • Standard key fits a 6″ max barrel length. Long keys are available by demand

Long Keys available for:

      • .22 LR auto:10.25 max barrel length
      • .380/9mm: 0.25 max barrel length
