The Pfeifer Zeliska 28mm Revolver is the worlds most powerful handgun but it is also pretty worthless because its too large to use effectively as you would a normal pistol. I would just stick to the Smith & Wesson 500 mag its something you could actually wear on your side like a pistol should be carried.
An assault rifle is, by definition, a select fire weapon which fires an intermediate cartridge, and is generally designed for ranges of 300 metres or less. In this regards, there are only a handful of cartridges which are used by assault rifles. They include:
Several cartridges have been designed, such as the 6.8 Remington SPC, 6.5 Grendel, etc., but have not seen widespread military service. Out of those four cartridges, the 7.62x39 would be the most powerful, which would give an edge to weapons such as the AK-47 and AKM, Type 68 and 81, and Vz. 58.
Rifles such as the FN-FAL, G3, M14, etc., which fire the much more powerful 7.62x51 NATO cartridge, are classed as battlerifles, rather than assault rifles.

A VERY good handgun- for most puposes. Durable, reliable, accurate, and powerful.
Probably, almost certainly, the .600 Nitro Express is the overall most power handgun bullet. Let me alter this answer by saying the .600 Nitro Express is a rifle round that one company made a pistol for. The most powerful handgun cartridge is the 500 S&W Magnum.
Eminent Tech TRW 17 is the worlds most powerful subwoofer.
Not even close. There are several more powerful handgun cartridges, not counting the single shot pistols that use rifle cartridges. While Dirty Harry may have proclaimed it to be "The most powerful handgun in the world"- it is not.

the most powerfull locomotive is soviet 2TE126
There are many handgun rounds that exceed the 44 mag. 454, 460, 500 to name a few.
Fairly certain it is the Thompson Contender .600 Nitro Express for production firearms.
