Need help with a magazine spring issue

[U.S. Patriot]

The mags for my FNP will not lock the slide open when empty, at least not the ones I keep loaded. I have contacted FN, but there customer service is a joke. No one makes an aftermarket spring, I have already contacted Wolf. What I'm looking for, is if someone with a Sig 229 could post a pic of a mag spring for me. The mags are similar, and I'm hoping the springs may be as well. I would really appreciate it.

Google has the pictures.
