Does anyone have any data on the terminal performance and risk of overpenetration when using Federal HST or Winchester PDX rounds out of a 16”, 9 mm Colt AR? My suspicion is that the ballistics have improved compared to data 10-15 years ago.

I rather not use a NFA SBR in 5.56 NATO with a suppressor for home defense unless I had to for obvious reasons. A 9 mm or 45 ACP PCC with a 16” barrel with the right loads may be a good alternative that will get the job done.
