Can anyone tell me what the purpose of the “extensions” on these recoil spring guides are for?

Maybe for a dual spring?

Recoil buffer?? I actually have no idea. Along for the ride on this one.

Old timey 'buffer'.
Of dubious value.

The above used springs.
Perhaps there would be value in a hydraulically (sp?LOL) dampened unit?

I would be interested to see what else went with it. So the “extension” was a guide for a smaller diameter spring that was inside the recoil spring?

No.
The smaller diameter front rod is a spring loaded plunger.
It crashes into the front of the recoil spring plug and softens the crash of slide to frame.

It's the damn Russians again!

Oh, that’s interesting. So they are complete as is.

Thanks, I don’t think I would have figured that out.

So, what is the purpose? I know this seems dumb to ask. I can’t see how this would slow the slide down without being a really stiff weight/spring rate. Commenting from a position of sheer ignorance again.

The internal springs are quite heavy. The main issue is they put strain on the thin ears of the bushing since they impact the recoil spring plug on every shot.

These devices were developed in the 40's/50's for bullseye shooting and to help protect the frame a bit while shooting lots of cheap USGI hardball. That era also created the first extra-thick bushings! These units were popular until the late 70's. I have seen many a Pachmayr or Kings 1911 with one installed.
