There are several on gunbroker in the $600 range, so I don't think those are overpriced . . . but they are used trade in guns so that distorts the issue. When I wanted to suppress a .45, I could have gotten most standard .45s and added ~$200 for an extended, threaded barrel or gotten the ready made HK Tac. They seem to cost more now, but my HK Tactical was a better deal at the time than adding a barrel to other guns, so I thought it was well priced. In general though, I think their new guns are expensive for what they are.
