The Integral Locking System (I.L.S.) replaces the mainspring housing of the handgun and when engaged prevents the hammer from moving by locking the mainspring cap, making the gun inoperable. It does not require any modification to the handgun. Comes with two keys.

Technical Information

Material: Steel

  • Totally disables a pistol by preventing the hammer and slide from moving to the rear. If the hammer and slide cannot move to the rear, the pistol cannot be loaded and/or cocked and fired.
  • Checkered surface for non-slip grip.

  • Replaces the mainspring housing of the pistol, is easy to install and does not require any modification to the pistol.
  • Fits all models of 1911 style pistols.
  • Two keys provided.
  • No instructions included
  • Please note: The mainspring cap pin is removed and put aside in order to replace the mainspring cap with the new one provided. Once the new mainspring cap is installed, the mainspring cap pin is NOT re-installed. When placing the mainspring housing back into the pistol, make sure the locking mechanism is in the unlocked position. You will be compressing the mainspring, (16 lbs on the Government model, 22 lbs on the Officer) so this will take some pressure.
