Porting is much more than drilling the barrel. I suggest that you send the gun to Mag-na-port. They use EDM machines to make the ports (which means burr-free bore). They have the fixturing to hold the gun in the proper position. My customers have never had a complaint with Mag-na-port's work.
Clemson thank you for get back with me on the magnaporting. I got with Gary over at Oakridge Custom Finishing and he said he deals with Magnaport and will send it off for me.
