Aftermarket barrels for P320 slide differences
Does anyone have experience with an aftermarket barrel on their P320?
I purchased a Silencerco threaded barrel for my M17, it didn't fit properly. It would not fit flush in chamber like the factory barrel does.
Is there a difference in the slide of an M17 vs a regular P320 slide?

I bought a threaded Silencerco for my P320 FS 9mm late last year. It shot about 3" low at 10 yds, without a can. Put the stock barrel from my other P320 FS on and it came right back on target.

I talked to them at their booth at SHOT and they offered to check it out if I sent it back. I haven't done that yet, so it's on me to follow up with them.

I also want to verify some measurements on it.

I shot my 320 compact with my Silencerco barrel last week. It was balls on.
