Does anyone make a P320 FCU spring kit? I'd like to have one or two handy when I start tinkering with the FCU. I know GrayGuns does a competition spring and trigger set up, but I don't want lighter.

I’m not aware of kits, but you can place a small parts order with Sig.

Thaks Pete!

You can also try the Sig Guy. Com - pretty good to deal with and haas what you want.
