If you have a suppressed H&K USP Tactical, then you have to have this barrel. It allows you to use the same suppressor on your Glock 21 and the folks at AAC have even made some improvements such as slightly easing the chamber to improve feeding of your favorite .45ACP load.

Thread protector is snug true drop in replacement. I used an S3f solutions barrel and the thread protector would often come loose even without firing not the case with this barrel. They are basically of the same composition so the snug thread protector makes this barrel slightly better.
