I think Todd nailed it. I have heard many of the same complaints about parts availability but my understanding is that has improved over time. It is hard to justify calling Hk's "junk". I am surprised the gentlemen who was calling them junk has such high regard for Para's LDA platform????
No firearms manufacture is without fault but in my opinion Hk's quality speaks for itself.
It also appears from Todd's P30 test that they are far from junk and that their service has been excellent.
