Hello everyone. The wife and I are wanting to understand her new BT380 a bit better. We referred to the owner's manual but perhaps overlooked it. When the manual safety is all the way up, red is dead, the pistol is in normal firing mode. All the way down when the red dot is covered it is in safe mode, and also decocks the hammer. However, there is a middle position where the red dot is still visible and the firing pin is still live (so we think?). What is the purpose of this middle position? Thanks.
