When Omi tries to take Blackthorn's pistols from Fuji, Fuji cocks and points one of the pistols at Omi. When the camera angle is from her left front, the cock is at half cock. The camera goes to Omi, then back to Fuji, and the frizzen is now forward and the cock in a fired position (but the weapon has NOT been discharged). The camera angle goes back to Omi who bows to Fuji, then leaves, When the camera goes back to Fuji, from her right, the frizzen has been pulled back to over the flash pan and the cock is back to half cock. Then the camera goes to Fuji left and the cock is finally at full cock and ready to fire. All of these moves were made without Fuji ever touching either the cock or frizzen.
When Omi tries to take Blackthorn's pistols from Fuji, Fuji cock's and points one of the pistols at Omi. But the pistol remains at half cock, and therefore inoperable.
During the intimate scene between Kashigi Omi and his lover, a nicotine patch is clearly seen on Kashigi Omi's upper left arm (closest to camera)
Blackthorne was supposed to give both weapons to Koki. You can see he has one in his belt when he leaves with Omi and the guards.
