ShapeShift Thumb Release for IWB

Trigger protection is a key factor to safe carrying. Our ShapeShift holsters make this easy: a full shell configuration will maximize the enclosure of the trigger and trigger guard. While half shell configurations, such as our 4.0 IWB holster, need our added trigger guard. You can use your thumb release on most half shell configurations thanks to this trigger guard, allowing for even more security through added retention.

To use it as such, you need to remove the thumb release from the back of the shell first. To do so, look inside the back side of the shell, just inside the trigger guard window. There you will see a flat head screw you can use the Allen key to remove.

You can then attach that thumb release to the provided trigger guard, using that same hex-screw.

The trigger guard then slides onto the front half of your shell and locks in with the Twist Lock. Attach the shell to the holster base, and you are good to go!

With IWB holsters (ShapeShift 4.0 and Appendix), you may need to make some adjustments in how the thumb release sits (or doesn't) on the neoprene base.  This may need a little trial and error to figure out what works most consistently to where the holster is worn on the body and the draw style.  Most folks find that the thumb release provides a more consistent draw when off the base entirely, which can impact comfort.  Other factors can include whether or not an undershirt is worn, size of the pistol and cant of the holster.

To adjust the alignment of the thumb release to the neoprene base, the screws holding the Holster Connector to the neoprene base will need to be readjusted.

In this example, the top screw was moved to the right hole, which shifted the thumb release more off the base.  One or both screws may need to be adjusted depending on the firearm.  Our production crew sets the pattern based on the firearm itself to ensure a good combat grip, so the pattern will vary from model to model.
