Very well made.

Wow this is my first aftermarket barrel and I am impressed with the accuracy. Much better than the stock P320 compact barrel.
The grooves are much deeper on the Grey Ghost barrel and it works perfectly and fits very well. When I first got the gun I thought the grooves were shallow and I guess I was right. It is certainly worth the money as a true performance upgrade and I am sure the slight length increase helped too but I feel the deeper grooves made the biggest improvement.
