What are you starting with? If you have either an X5 or X5 legion trigger bar (they are different than each other), I think you will prefer them over the Apex when used with an adjustable trigger.
I tried the apex bar with the AC trigger and while you could almost eliminate take up in the trigger with that combination, it increased the distance from take-up point to when it would actually fire (and pull weight was 4lb 6oz). I didn't like that and went back to the X5 bar. So with the AC trigger and an X5 trigger bar it is 3lb 5oz (in a P320C trigger unit).
BTW, for me the legion trigger and bar with GG kit (minus trigger) is 2lb 10oz, legion trigger and bar with just GG sear springs is 2lb 14oz.
