Ah yes, the SAR K2-45, and I've had one for about four years now!
We often discuss them over in the Cz Clone area and there are quite a few threads there on it.
Excellent .45 Pistol, but I still prefer my Tanfoglio .45 Witnesses to it. It is accurate, reliable, and better built than most Tanks.
I only have two criticisms of it.
1) It's heavy, especially when fully loaded. Try carrying one all day. I only did it once.
2) The Grip is fairly large for my hands, but it probably has to be to hold 14 rounds of .45 ACP.
