The color or appearance of the striker cups will not affect the functionality of your firearm with M*CARBO parts.

The Sig P365 normally ships with black striker cups, but the recent introduction of white striker cups has caused some confusion. The striker cups are exactly the same in terms of functionality, with the only difference being their appearance.

Therefore, if you are using M*CARBO parts in your Sig Sauer P365 or P320, you can rest assured that they will still work perfectly fine regardless of the color or shape of your striker cups.
