I have an M&P Pro. The pro's are 4.5lb. Will the Apex hard sear lower that? I would like a better feel, but dont really want it to much lower.
I put the Apex competition kit in my Pro. It is significantly lighter, cleaner, with a more positive reset. If you want to maintain a 4.5-5 lb pull, I believe you would want to install the Mass trigger return spring instead of the kits. All the benefits of clean takeup and break, with less trigger reduction and even more improved reset. I would ask Apex about this myself though, since I haven't tried it personally I can't say for certain.
