Posted the final update for these. +2 magazine extensions for the P10 C! They sit flush with the grip and come in 3 different sizes to match your back strap. They use the stock steel retaining plate from the OEM +2 extensions, so no need to buy anything to install them.
They're solid and held up to 2 IDPA matches and a Steel Challenge.
Find them on my Odysee page under the same name.
