I bought the M&P 9mm Performance Center Ported CORE 5" several months ago to make an entry level USPSA competition pistol. The ports helped the muzzle flip.
I found the accuracy was unacceptable, got an Apex SDI, and it's 3" at 25 yrds now. But, I lost the advantage of the ports.
Apex customer service warned me off of porting the Apex barrel when I talked to them about. I never got a clear answer why not, except the normal concerns about losing accuracy with porting, which I believe has been debunked.
Has anyone out there ported their Apex barrel in their M&P 9?
