I realize that this thread in no way concerns the use of boolits, but do hope I will be forgiven.
I recently picked up a Beretta 92FS in used condition and, of course, with no manual. I have noticed that when the decocker is put into the 'fire' position a slight trigger squeeze will bring the hammer back to a 'set' position removing the firing pin from contact with a primer.
My question is, is this a safe way to carry this pistol or should the decocker be engaged at all times unless ready to fire?
