I can't find the post now, but wanted to thank whoever recommended swapping the stock hammer spring for 17lb ones from Wolff on the Sphinx SDP Compact...just received mine today and swapped them in and it makes a big difference on the double action pull! This is a fantastic trigger out of the box, but this is a cheap and easy (Sphinx Hammer springs are incredibly easy to swap) to put the cherry on top.
So, again, thanks to whoever suggested it!
