It is quite a good weapon.
The textures are remarkable.
However, I do criticize, if you are trying to make it close to the original, the barrel of the gun is far too long, and too narrow.
In the original it is more compact and wide.
What you have done, is amazing, just not to the original.
I am not trying to be mean, I am just saying what my eyes see.
Thank you,
