I got a CR Speed WSM2 from Sean at Freedom Ventures. It's a special WS2 version that fits the GP Mark 12 version that have a wider trigger guard. The normal WSM2 will fit your Mk7 just fine. I really like it for IPSC, but it's not as secure as a drop in holster. I have knocked my gun off my belt once during practice, so I just have to be careful to make sure I lock it down when I'm not shooting.
Looks like ShooterReady lists a LHS holster for the K100, but you should check with him to see if it's for the Mark 7 or Mark 12. http://www.shooterready.ca/shop/rapid-draw-holster/
