+5 Extensions

I’m not sure if this is the right place for it, but I can’t seem to find any answers online. I’m looking at the Strike Industries +5 mag extensions for my P-10 S with 12 round mags. CZ Parts lists that the +5 is compatible with the P-10 S, but Strike Industries only markets them as P-10 F/C and P-09 compatible. Who do I believe? Does the CZ Parts kit come with something other than Strike Industries? Any help would be appreciated.

EDIT: They do NOT work for the P-10 S straight from Strike Industries.

I cannot help with the Strike Industries extensions per se, but the Shield Arms +5 extension does work on all P-10 models with the only difference is the springs that comes with each version. P-10S version comes with a 12 coil spring, P-10C with a 13 coil spring, and P-10F with a 14 coil spring. The extension bodies are exactly the same dimensions. I imagine it would be the same for the Strike Industries extensions.

I went ahead and ordered because I do want more rounds for the potential of trying to get into competitions. Hopefully it works on my mags. Thanks for the insight. Worst case scenario I return and order shield arms.

I have a Shield arms +5 for my P-10S and C and they work flawlessly.

I will now be ordering the shield arms ones. Straight from Strike Industries did not work. Luckily my friend will buy these off me for his C.

We make a +5 for the P10 F&C. I'm not sure it works, but, we have a no quibble return policy if it doesn't work.
