P-10c Recoil spring weight for light minor power factor?

I'm shooting 147gr plated lead bullets at 880 fps.  Ejection is very weak with the stock spring.  I was thinking 13lb would be a good starting point.

I'd pick up a 13lb and 15lb and give both a try.  OEM spring is too much even for shooting standard range ammo really.

Where are you sourcing 13# springs for a P10C?  CGW sells the 15# flatwire.  If I could find a 13# I?d try it.  I?ve tried using Glock 19 springs but that didn?t work (slide didn?t feel like it was locking up), and tried Glock 17 springs but they stacked and slide wouldn?t lock back.

I have a selection of Wilson Combat 9mm 1911 springs that are the correct diameter.  One I have the guide rod I will check fit and function.   I will start with the 15lb spring from CGW though.

We've used Glock 19 springs for the P-07 for years and ever since the P-10C came out, for that as well. Never heard of an issue.
The recoil spring assemblies on all 3 guns are essentially identical. There's no reason not to use G19 springs.
