I have 2 Para-Ordnance LDA 9mm 1911s.

I also have almost 1000 rounds of Pierce factory ammo that shoots well except it has hard primers. I was able to shoot the ammo fine out of a PPQ and an H&K.

So my question is, anyone know how I can firm up my primer strikes? Not sure if the LDA 9mm 1911 firing pins are any different, and even if they aren't, are there differing spring rates for firing pins?

Thanks,

The firing pin spring in a 1911 is used to retract the firing pin after the pistol is fired. A proper strength FP spring will also keep the pistol from firing if it's dropped.

Power to drive the FP forward comes from the hammer which is driven by the mainspring. That's part #29 in the below link.

Genius

Quick update.

New firing pin from Dawson Precision in Florence TX got new straightened out perfectly.

Gun is running 100% with all ammo.
