Kral hardened sear from JSAR

Anybody have the JSAR hardened sear in their gun? The only thing I don't like with the Kral PB is that I can't quite adjust the trigger to be as nice as my Daystate Regal. I've got it pretty nice, but it's not quite there. I've heard that due to the angle of the stock sear, when the trigger is pulled the weight actually gets harder due to the sear trying to push the hammer rearward just prior to releasing. If this sear gets rid of that I could almost justify paying the $$ they want for it. If not has anyone "re profiled" their stock sear to get a lighter pull? If so, what exactly did you do?
 
What i idid on my kral is firstly change the 1st stage spring for a lighter one and then polished all the contact points in the trigger group, now i dont have a gauge but in reference to a friends tuned up gamo coyote which has a "hair trigger" the one on mine seems to be about 1 pound or less at the second stage since i just touch it and it goes off
