It's not the very first model who attached a scope to the default deagle but i'm impressed by how it turned out.
The texture on the scope looks dull, just a square with a blue circle in it. Try to find a way to fix this, better expand the scope circle or to change the square's color to something more similar to the scope's body
You have many UV errors like this one in newparts.bmp:and to prevent any other issues to appear in the UVs, try this compiler: Link
I like how you edited the idle animations, though it can be improved even further
There also other issues in animations like when the animation moves from shoot or reload to idle, the model position changes a bit. I know those are default Valve animations, I'm just mentioning it ..
The other part of the scope is removed and it's easily noticed on draw animations
The textures of the hands are badly sized, you must always have textures sized in powers of 2 (32, 64, 128, 256, 512). So the textures must be resized as: .. view_glove: 256x128 ... view_skin: 256x256 .. view_finger: 128x128
PeeWees are good enough, but has the same UV issues i mentioned before
