Anyone have one of these?  I have the SAR K2 .45 and think it is an awesome CZ clone.  Is the ST-10 an awesome HK clone?

awesome? hardly.  Pass, they are overpriced and most places are selling them off as I think they are DC'd.

Under $350.00 doesn't seem overpriced.

well, when you consider other firearms in 9mm at that pricepoint it is.

Magazines are virtually unobtanium - the catch cutout is roughly 0.10" higher than a CZ-75 (or all the other other SAR 9mm models) so it'll fit but won't lock in, and there's not enough metal left to make a new cutout. Nobody ever seems to have them in stock (or at least not when I'm looking).  Had mine for a couple years now and still have <150 rounds through it.  Nothing wrong with it and it's worked flawlessly but it's an afterthought I usually don't bring to the range...I still have a NIB K2P for the same reason.  Sold my B6P because I preferred the B6PC - which DOES make every range trip.
