I suspect in the near future you’ll be looking for recoil springs.

Fortunately they are the same as the Chief Special .40 & .45’s. Unfortunately they are the same as the Chief Special .40 &.45’s.

After calling both S&W and Wilson combat, unsurprisingly, neither could offer any constructive information. I was told by S&W they don’t offer the service of fitting ambi safeties for this weapon anymore.
Wilson has no idea what a Smith 945 is. So armed with Jim’s information, I measured my 945 frame and that of a Colt military 1911 I have. The difference was @.007 in width. The slot/blade configuration of the Wilson safety should make this a workable installation, providing all else is compatible.
Nothing ventured, nothing gained. It is reversible at any rate, and if it works, others may find value in it.
Thanks to all for your valuable input. I will follow up if it works.

See posts #17 & #19 for alternative recoil springs for the CS40-CS45s in this forum thread:
