Thanks for the input from everybody. Much appreciated it.
Mustang, what is the anticipated turn around time for your custom Shadow?
Just wondering, if the main spring plays no part in the SAO pull weight, what can be done to reduce the SA pull of the Shadow ? Trigger return spring?
For myself, I am a bit concerned about the weight of the SP01 or Shadow, especially if I have to shoot w/ my weak hand.
Tac light and laser (unless it is an infra-red one) work both ways: allow you to "see" the BG but he can also "see" your position. If I were a BG w/ a shotgun I will just aim where the source of the light is and shoot. As such I really do not need a rail.
