The Japanese Type 94 is probably the worst pistol ever devised for military service. The sear is exposed on the left side of the pistol. If you touch it the pistol fires. Additionally the ergonomics are horrible. I added it to my collection many many years ago when they were selling for $15 only for laughs.
I remember seeing an officer using one in Clint Eastwood's film "Letters From Iwo Jima"
