Actually, they are not bad pistols with good ammo. They were one of the guns the Japanese sold, mainly on the Mexican and Latin American market, before WWII. They got an interesting reputation when some armchair warrior discovered that with hammer cocked and the safety off, the gun could be fired by pressing the sear bar on the left side.
That led to the nonsense story that a Japanese officer would pretend to surrender and approach an American with the pistol held with his finger off the trigger. Then, when close enough, he would press the sear bar and either 1) kill the American or 2) kill himself, depending on which war story the listeners wanted to believe. So the gun got named the "sneak pistol" or the "suicide pistol".
Silly, of course. No Japanese, officer or private, with a gun in his hand was going to get anywhere near an American Marine or soldier no matter where his finger was. Further, the Type 94 was issued mainly to the Naval Air Force, so unless the Japanese gentleman was walking away from his plane at the time, he would likely not have a Type 94.
