Another reason is the pistol can be accessed faster because the gun is in one set position. In a standard purse without a holster, a person has to search in the purse to get their hand on the pistol. This can cause a problem because if the gun is needed quickly, it is not accessable fast. This is not the case with a gun purse.
The gun purses to the right, have a holster built in the purse. Access to the pistol is fast becaue the hand fits right into the zippered opening that holds the pistol. If you want to purchase one of these, just click on one of the purses to the right.
