lol that is not bigger than the .50 BMG like he said dumb ass probably ment the .50 AE

Not really best. But powerful.
My personal favorite pistol is The TT-30

lol the .700 nitro express is for a rifle that whole video is fake btw 900 grains for a pistol? haha ya fucking right

This is an impossible question to answer, as it has about a million different answers... You just want the quick answer... Instead of saying what is the best handgun... Maybe you should expand on that question... Like what is the best handgun to conceal... Or what is the most accurate handgun (in terms of grouping sizes)... Not just "What's the best handgun"... Also do a little research before you post information...

Also that youtube video is kinda dumb... It quite possibly may be the most powerful handgun, but why the hell would you need that much power from a weapon that is so unsafe and uncontrollable...

Proably to compensate the size of your dick or something =)
Most likely one of those macho crap things.

its not a real pistol. the bullet is so big as it is going down the rifling it would twist the pistol right out your hand and probably break it haha

i think a taurus tracker 44mm, is pretty powerful also and i think desert deagle .50 cal are powerful no matter what ... but fir the TT 44mm recoil sucks ass if you don't know how to use it, it will come smashing to your face. but its possible to fix so will the 50 cal if you don't know what your doing

makarov is an amazing pistol as well the holster for it is what puts it over the top imo

My handgun is the best because it's mine.
