I gotta chime in on this, lets examine how the SIG trigger system works. The system includes a double action first shot requirement, this pull is about 12 lbs, next the SA pull is only about 4 lbs, this is completely unsafe for carrying without a safety locked. Therefore you MUST use the decocker to reset to double action or risk shooting yourself or god forbid somone or something. Also the SIG system includes a fireing pin block and safety intercept notch, both of which can only be disengaged when the trigger is just short of fully pulled. While in the single action position, it only requires a slight press on the trigger to discharge the weapon. This situation is NOT safe for a hammer cocked carry. This is all completely outlined in the manual, please read it. The decocker is not a "feature" and the Double Action/Single Action trigger is not an "option" that you have. If you are going to shoot a SIG, or any other DA/SA auto with only a decocker, LEARN THE TRIGGER, DA for first shot, SA for follow ups. Practice, learn it, if you cant do this, ditch it and get another weapon more suited to your tastes. Your health is on the line.
