I had a Tisas stainless HP clone; it never functioned reliably, regardless of what the fanboys said. Down the road it went.
I've seen the Girsan M9 clone in a LGS, it looked well made (but then again so did the Tisas). I hope their HP clone turns out to be a good one. FWIW my Mk.III shoots very well, as does my 70s vintage HP with the "beer can" sights.
