Perhaps no other gun on this list over promises and underperforms like the Apache pistol. This pistol appears to combine the effective ingredients of a knife, brass knuckles, and a small caliber revolver into a neat, fold-out package.
In practice none of the three components of the weapon deliver.
The brass knuckle component works well enough, but the knife is thin and flimsy on its hinge. The revolver, with virtually no barrel to speak of, is terribly under-powered and inaccurate.
Additionally, because of the unguarded trigger, the user is likely to accidentally fire the weapon often.
