So I bought the P226 Sport compensator out of the classifieds that I believe is actually an aftermarket P220 compensator, but that isn’t a bad thing as it can go either way.

Is there a sensible way to machine a railed frame down to the little German Rail that was on the sports?

Is it a lost cause?

You can machine down a stainless frame.

An aluminum frame would need to be milled and refinished.

Not sure if it would be worth the effort required for either one.
