I don't have the HK45 (yet) to measure, but all of the specs I've seen on the barrel list it as 4.53" long. The USP 45's is listed as 4.41". It would be nice if they were the same, but H&K's web site specs suggest otherwise ????For example, the full-size HK45 barrel is the same as the full-size USP 45. [/b]
I think that this must be tested before we know for sure....the full-size HK45 barrel is the same as the full-size USP 45....
I concur; I have a spare threaded barrel. If it fits, I bet more folks will be interested in an H&K45. I know I would. But if they're not it certainley hasn't dampened the demand.All I know is what I read in Mr. Hackathorn's article. Maybe something changed from when the article was written but that would surprise me.
- At least one member of HKPro has installed an LEM kit in his HK45 with no reported issues.
- We have already been told that some USP mags work fine.
Somebody must own one of each (HK45 & USP 45 Compact & USP 45 full-size) by now. All we need is for them to look for us and settle the matter.
