Great drop in barrel
I picked up a non-treaded version a while back to build my own P320C. The barrel is drop in and had no issue. It is more accurate than the OEM barrel and a reasonable price.

P320 Compact match Grade Barrel Rocks
I had several P320s. I rarely carry my 40 and wanted to covert it to 9mm. I have an X Compact that I had made out of a sub compact. So, I decided to pick up a Sig FDE slide and needed a 9mm barrel. I decided on an aftermarket barrel from Grey Ghost. The fit was perfect and required no gunsmithing whatsoever. I coupled it with the slide with Meprolight R4E combat sights and a Sig skeleton trigger. At 15 yards, I can keep groups to 2 to 3 inches. The barrel delivers consistent accuracy and I have not experienced one malfunction. I didn't even realize the barrel price was discounted until I checked out. That was a nice surprise as well. If you are building your own Sig or just want to change caliber, this is a great buy. Five stars because my browser would not let me click on the stars.

Sig P320 Compact Match Grade barrel
I got to try out the barrel at the range today. The barrel is well made and has a unique look. I put a couple of hundred rounds through the gun today with no malfunctions. Groups were as good as those with my P320X Compact and probably would have been a little better since the new Sig slide had standard sights. There were no malfunctions. It was drop in and did not need any custom fitting. Very pleased with the purchase.
