Try a P15 before deciding,I had always dismissed these as Chinese junk But after coming across one they are super accurate and featherweight. super tuneable simple to work on and customisable beyond belief.
If you have a relevant slot on an FAC they also can be without too much hassle be tuned to 40-50ftlbs easily.
I have one in .25 cal fitted with a Walther Barrel and Huma Regulator with FAC spring.
