Stats for Scout:
Pros:
+60% damage on point blank shots (max damage 96 and critial hit max doing 192)

Cons:
Only shoots 1 bullet per shot (its a revolver of course)
-15% reload speed

Stats for Spy:
Pros:
+Mini crits enemies using melee (For example: engineer trying whack you with his wrench)
Cons:
-20% slower reload speed
-20% slower firing speed
