Now that I have my P10S/OR, I’ll go the custom cut route next time. The optics ready pistol is a great gun for someone that does not know if an optic will work for them, but if you decide that it does, the custom cut is a better solution. The optics ready guns require the sight to sit higher to make room for the plate and the plates are an not well fit. It works, and I love my P10S but the P10Cs that I have will get cut if I add an RMR to one of them.
