1911 holster question
 

From http://www.ebay.com/itm/Colt-1911-45...21162659933%26

Could someone tell me, please, what the structure inside the holster is/does?

Thanks,

D.P.

Allows the user's full trigger finger into the trigger guard and onto the trigger faster. It holds the frame away from the back leather. You can see how the trigger guard is centered when the flap is closed.
