Pros:

good model
new sounds
nice new feel for old gun
works with other shotgun mods

Cons:

not much of one, but the little laser box throws me off sometimes

Conclusion:

the Doktor is in, yet again

Pros:

*Fun idea, gives a new feel to the gameplay as the magnum is so very useful.
*keeping 8 shots in each gun gives good balance, not terribly overpowering

Cons:

*as soon as you pick up a 2nd pistol, it puts both your hands up, and act like there are 2 magnums, but it only shows the one in the right hand, there's nothing in the left.
*If you turn on custom magnum skin, as soon as you pick up 2nd pistol it turns back into standard Desert Eagle, and the 1 gun, 1 empty hand thing happens again.

Conclusion:

Fun idea, and the reload, clip count and sound all works.  Needs scripting fix on custom skins and left hand gun.
