FWIW I believe they are stronger, currently, even with the use of forged/milled Stainless Steel slides, which should be heavier than the older folded Carbon Steel slide with removable Breech Block. But then again, the newer models are able to support +P ammunition.I've noted that some of the older models seem harder to rack then later production. Was there any change in recoil spring on newer versions?
I believe he's only referring to the P225 (not A1) which does not have a stainless steel slide. I have a 1981 P225 and a 2009 P225 and both are built exactly the same--same mainspring assemblies also.FWIW I believe they are stronger, currently, even with the use of forged/milled Stainless Steel slides, which should be heavier than the older folded Carbon Steel slide with removable Breech Block.

I "assumed" OP was talking about Sigs in general, and I was considering the W. German models compared to newer US manufactured models of same Model #... and we all know what assuming does...I believe he's only referring to the P225 (not A1) which does not have a stainless steel slide.

If he's comparing to the newer A1's then that's totally different. The new A1's have a P239 recoil spring which is not a multi-strand spring.
