I just installed a curved PELT in one of my P320s tonight. The trigger pull is a couple pounds lighter, as advertised.

However, the trigger reset length is also noticeably longer now. I don't have a way to measure it, but in comparing it to my unmodified P320 as well as my memory of the previous pull, it seems about 50% longer.

Is this normal, or did I mess something up with the installation?

Yes, It is simple mechanics. The trigger is essentially a lever system. The trigger is the effort arm and the part that extends above the fulcrum (axle) and connects to the trigger bar is the load arm. The Gray Guns trigger reduces the trigger pull by shortening the load arm compared to the stock trigger. The trigger bar still needs to move the same distance in order to activate all of the sear functions.

Since the load arm is shorter, the effort arm (the trigger) must move further in order to move the trigger bar the same distance. With all of this in mind, it also increases the distance between initial sear contact and sear releasing the shot and the distance after the shot fires before the sear resets.

The new Apex reduced effort triggers uses this same method, but the load arm is not quite as short as the Gray Guns trigger, so the pull weight reduction is less, but so are the distance changes.

Hiya! RichN is fundamentally correct. However, our (patent-pending) design has features which help us "cheat" on this, so the practical effect on reset length is not objectionable. Most shooters don't notice the +/- 13% typical measured difference. What you will notice, perhaps, is a softer feel to the reset owing to the feedback effect of that leverage change, and that translates to a perception that the reset is longer. It's really not. If you used our reduced rate trigger bar spring, that softer feel is accentuated, which is why we recommend the factory spring be used for most normal applications, and for duty. I thank you for trusting us with this component, and hope my explanation helps you.

Thanks guys!

I stuck with the factory trigger bar spring.

FINALLY! After all these years, we finally find out what "damn grease" is.
