Rimx magazine spring

Apparently my google skills are lacking… does anyone know where to get a replacement spring for a rimX magazine? I wouldn’t mind one a little stiffer than my current one, it’s slowly wearing out.

Wolff makes the current springs for the RimX mag so maybe start there...

I never had any issues with 10rd RimX mags but did with the extensions and would've like a longer/stiffer spring with extensions

Shoot me a PM, I’ve got two that you can have. Not 100% sure if they’re brand new or not but I changed mine out every year but no longer have a RimX
