So far, so good with the Alien Gear holsters. I've lost some weight over the past year and went down a pant size, but need to use the old size to accommodate their IWB (Cloak Tuck 3.0). The holster works well and is very secure and fairly comfortable. I've only had my permit a few weeks, and since I can't have a firearm on the property at work I've only carried a few times; but so far so good. FYI: I'm carrying a S&W CS9. They don't make a holster specifically for that model, but based on their recommendation I went with one designed for a 3913, and it fits fine. They've got a 30 day return policy, so really no risk.
The Cloak Slide (OWB) is also good, but it feels a little less secure. Not saying it IS less secure, just my impression. I'm thinking of getting something with some type of retention system (Blackhawk Serpa?).
Another thing I've learned; I thought I would want to carry at 3 o'clock, but even with the IWB I feel like I print pretty significantly. My pistol is much less noticeable at 4:30.
