Tactical has better sights. For me, it is hard to align the fibreoptic
dot with the rear sight. Even when I do, it shoots 2" too high.
Also, Shadow is not for people who are used to stronger triggers.
A very light touch of the trigger sets this gun off. Not very practical
gun. Maybe good for IPSC "speed" competitions, but not very practical
for other applications.
Tactical was designed for carry, military and SWAT work.
Shadow is a cute gun, but would I want to carry one if I could.
No! Tactical would be my pick.
It all depends what you want to train your hands for.
One can get used to either gun.
If anyone wants to swap their Tactical for my Shadow, PM me.
