I'm curious if the Apex sear would be any improvement in my PC Shield?

I'm going to buy a red Apex trigger, because I HATE the hinged S&W trigger. I figured I'd give the sear a try, along with a Glock trigger spring, and see how it works out.

The PC has a crisp break, but it seems to be mighty hard. I don't have a gauge, but I'd probably guess about 6.5 from experience.

Thanks!
