To the OP
Can you check them out at a firearm dealer/store before purchase? If you can, check the triggers (SA break) of a couple of SP01 Shadow. Some are so good (crisp, snap break, no camming or creep) that even competition hammer from CZC makes no improvement at all. You can always get Aluminum grips, short reset, competition hammer later on.
I have a full house modified sp01 in which I have added short reset from CGW, competition hammer (have tried both CGW and CZC versions), light springs, extended FP, cocobolo wood grips etc I didnt like the feel of the gun as much, and added SP01 Shadow safeties. Now, except sights, its almost a SP01 Shadow, but still not a SP01 Shadow ! The reset with the FPB is still long, although the triggers are equally good in break. I needed night sights, and hence opted for a SP01. If I were to redo, I would simply install night sights on a SP01 Shadow !!
If I had the money, I would go for a full house deal on SP01 Shadow, but if one wants to spend a bit less, then I would recommend the SP01 Shadow, bone stock. Having said that, you cant go wrong here whatever your choose.
