Beretta PX4 full size

Gentlemen, thank you for your replies! They have been most helpful.

There are several topics on the PX4 and I can't even find all of them on my phone - my apologies if this has already been asked and answered.

Beretta sells a part they call "Lighter MAX Hammer Spring for Beretta Pistols (Competition)", part # C90160. They say it is compatible with the PX4 but won't say the weight of the spring. Does anyone here happen to know it, or have experience with this part?

It is about 12.5lbs.
