The fire pin spring was lightened because on the glock, that partiallly dictates the trigger pull tension. I have never liked it on this gun so I spent several hours modding about 12 things in it to tailor it to my pref. I really like it right now but the pin spring might have to be returned to OE if I cannot get reliability from it.
Didn't we address this in another of your threads?
If you want 100% reliability from any striker fired pistol, keep a full power striker/firing pin spring in it.
If you want 100% reliability in any hammer fired pistol, keep a full power hammer spring in it.
The inertia of the firing pin strike is crucial. Manufacturers of pistols spend zillions of dollars engineering pistols so that they work. That is a clue.
For a fun gun on the range it may not matter, but for a SD gun it is a BIG deal.
