Erm, its a lovely model... but thats the wrong gun
i cant help noticing this, as the magnum was probably my favourite gun in the game...
The Cougar magnum is, in real life, a Ruger magnum. The Ruger Super Blackhawk .44/454 magnum, to be precise, with a 7.5" barrel and stainless finish- one of the worlds most powerful handguns, second only to the S&W M500.
This normally wouldnt be too much of an issue, as a revolver is a revolver is a revolver, but in this case there is practically no similarity whatsoever between the two guns.The model you've drawn up is the old Colt Python ultimate, a comparitively measley .357 magnum designed for shooting tagets very, very neatly. The Ruger is a WAY bigger ol' magnum based on the old western style revolver, with no swing out cylinder and an unmistakeable ejector rod (which can be seen on goldeneye is you aim far right with the gun). It is essentially a much larger, newer and more powerful version of the gun revolver ocelot uses in MGS, the Colt Single Action Army.
Python-
Cal- .357 mag
barrel - 6" in that model
Designed for- targets
Double action
has appeared in countless videogames!
Blackhawk-
Cal- we'll say the goldeneye one is 44 mag (a LOT more powerful as 357)
barrel- 7.5" in goldeneye, overall gun is 1.5 times size of the python
Designed for- big game and people who like insanely large guns
Single action only (must thumb the hammer back between shots, though it seems to be double action in goldeneye for convenience)
Has only been in one game, goldeneye! (id been looking forward to it being redone!) if you aim to the right with the gun you can see the ejector rod)
(BTW, the reason why the gun in the model looks like the one from Half Life is because the magunm in half life is a python! gees, those things get into all kinds of games... which is weird, because they really aren't combat revolvers. Mind you, the blackhawk would be even worse in a combat situation...
