Hello all,

I have a early 1990's P229 with its original long mainspring with metal seat. The decocker exhibits stronger than normal resistance when engaging the sear. That is, there is not much resistance to moving the decocker downward; however, once the decocker contacts the sear, it takes more effort than normal to engage the sear to lower the hammer.

I first noticed this after installing a new parts kit on this long unused P229. I tried using the old decocker spring and another decocker lever (4 combinations) to no avail. Looking at where the decocker engages the sear, I am wondering if the sear spring is too strong or the mainspring is too strong.

Your insight is much appreciated.

Thank you,
Ian

That should be mostly mainspring. If it cycles when shooting, I wouldn’t consider it too strong and leave it alone.

I’ve felt lots of variance in the decocker on various SIGs; as long as it decocks as designed, I’m good.
