I purchased a Shadow 2 in hopes that IDPA will soon let us use them in competition, but as of now, it has a light on it and fills the role of home defense.
If I were a SWAT or Spec Ops guy, I would look into the Shadow 2 as a carry option, because who wouldn't wan't to carry the best gun that woks for them, especially when concealment isn't a concern.
I would recommend removing the recoil spring shock buffer when not on the range, as to reduce a possible point of failure, should one come apart and lock up the gun during operation.
I have never seen, or had this happen, but it has been a common recommendation with 1911's and their after market shok buffs.
The fiber optic sights work well for me when the gun has a light attached, or I hold my hand held light next to my head. This aids in a natural way to keep the light pointed where i'm looking, and puts your support arm in a blocking position.
I've replaced all my night sights with fiber optic sights, because I found that night sights suck in outdoor dawn and dusk lighting conditions.
Ambient light is bright enough to eliminate the glow from the sight, yet is to low to easily acquire a sight picture from the iron sights.
This is what I have found that works for me, and others will have different preferences, so practice with what you have, to make sure it works for you.
As a side note; I would like to ask what the experienced members on the forum would recommend for the spring set up in the Shadow 2, for super reliable use with all 9mm ammo.
Since the Shadow 2 is designed for competition, I would assume that lighter springs are used, than what one would find in a regular 75B, and heavier springs may be more reliable for primer strikes and overall operation.
Thanks
