So maybe a strange idea, but can anyone tell me why an extended barrel wouldn’t fit on my XTEN Comp? I realize it would protrude through the port rendering it useless. But I looking at a 10 suppressor and Hush ammo. Will this work? Can’t think why it won’t.

If you are going to get a custom 10mm barrel made to fit a suppressor to, instead of worrying about that, just buy a slide for a .40S&W P320 Compact for use with the suppressor. If you're going to spend the money for this conversion, don't go cheap.
