I currently have an egw hammer and a harrison true radius sear. I run a 15lb hammer spring. Trigger comes in at 1lb 13oz. Took a lot of sear spring tuning to get everything set right and reliable but the combo works great.
As above either extend the decap pin or you are getting primer pull back. I Chucked my decap pin in a drill, sanded with 1200 grit and then scotch brite to polish, after I did this no more issues.
I like a quick return and flat, I'm looking at minimal dot movement rather than how it "feels" in the hand. Current setup is a 5.4 barrel 2x 3/16 popple with 2 port Binary comp. Load is 9.9 gr of AA7 at 1.165 using a 7lb recoil and 15lb mainspring. Gun is very flat in video and returns quick.
