On advice received here, got the HB trigger kit for the Scorp; brought the trigger break down to less than 6 lbs, with what feels somewhat like a two stage trigger. The first stage cams the firing pin block, and the second releases the sear. Not a Geissele, but easy to control. Installing the spring kit does require one more hand than most people have. Less than $12, even with shipping.
Now, MagPul is making a replacement pistol grip, more vertical and with better gripping surfaces. One screw, tap the OEM off and the new one on. The grip is two piece, held together with screws. Unfortunately, no storage space, and adjusting it for reach will leave a gap, but it feels much better than OEM. $25 and shipping.
Continue to be pleased with the Scorp. I've the factory folder; it would be about useless without a stock or a brace..
