Just got the Tulster for my CC9. I wanted a single clip and that's the only reason I went with the Tulster over Tenicor. One day delivery was sweet. Quality - It seems like it will last about a year for me, which would be great. It's durable but nothing like Garrett quality. I feel like my Garrett could outlast my gun. I have a Garrett for my SW MP Shield Plus Carry Comp which I can't carry AIWB.
Bottom line is the Tulster works well for AIWB and is way better in every way than anything else I tried. I would try a Garrett for this gun but I'm not waiting a other 2+ months for a holster. Also, the last holster I bought from them didn't fit my gun at all and I had to return it with postage paid by me! So unfortunately, as much as I like their holster, I won't be buying another Garrett.
