Older TSS – have these internals been updated?

I purchased my Talon SS around 2001, and am looking to update all internals to the current shipping version of the SS. While ordering parts from Air Force recently, I got an updated hammer, thinking it was a drop-in item. However, judging from the size and weight difference from my original plastic one, I’m assuming there have been other changes to the spring/spacers. I’m wondering what else I need to get.

Also, have the bottle’s valve components gone through revisions?

I thought I was pretty good at “Googling,” but haven’t been able to come up with any parts list or diagrams for the current shipping SS. Thanks.
