same hammer spring, same recoil spring, same sear spring, same mag catch spring, same firing pin spring, same slide catch spring, same mags. Sights are also interchangeable. Slide stop is not, mag catch is though, but probably not IPSC legal if that matters.
"lessen the take up" what exactly do you mean by this? Lessen the weight or the distance? I prefer the 11lb mainsprings (also known as hammer springs) I got from CZ years ago, but they don't sell them anymore. the next best is the 11.5 from Cajun Gun Works (not IPSC legal). You can also get an 8.5lb from CGW but need to use Federal primers with that one.
If you want to reduce the DA length of pull, well, you can't.
