Great choice! Its what I continue to use. Very comfortable and the WML does not inhibit carry. If you go with the Surefire X300Ultra, he should have the mold for it since I was the first person he made one for.
yeah I had to dash out of the office but wanted to comment. you picked an excellent, excellent guy for a holster. Kee's holster is just too good. I've got a review on here somewhere that goes into further detail.
