43c .22lr firing pin

I have 2 43c Smiths..
While cleaning, I noticed that the more resent has a solid firing pin and the older one has a hollow, reduced mass, pin. First hollowed our pin I’ve ever come across! WHY?

I'll guess it's cheaper. Might also have something to do with making the gun "drop safe" but I can't imagine the solid pin having enough mass to overcome the spring and still be able to percuss a primer in any type of normal scenario.
Maybe someone knows for sure.

You might get more information if you post this on the S&W forum.......

News !
The older S&W 43c with the low mass firing pin reliably fired all the CCI stingers / Quik Shok rounds. 😁
This is with an 8# hammer spring !
My other 43c & 317’s required 9#.
11# rebound in all.
(Stock 12# hammer, 16# rebound. )
Much better action. Really.
