For me, it was a mixed bag. I wanted to like it, but I could not. I ordered one for my concealed carry gun, but after drawing, it would not stay open. I am not sure why, other than I have about 20 pounds more than I should. The holster seemed of good quality, but not stay open. I am not sure if this is typical of this style of holster, but it was a no go for me. I almost think the kydex shell was too shallow. The Kydex part only covered about half of the width of the gun. It might be fine for someone else, and/or if you adjusted the spacer or something it might make a difference, but I did not fool with it.
Your experience may be different.
I will say it was very comfortable.
I am also not a huge fan of trying to hook the floppy leather and clips onto my belt/pants while trying not to drop my drawers. I do not feel like I have enough hands to put one on. That is my personal problem not necessarily yours and that really would not be different than with a Cross Breed, or any of that type, but it will tell you a bit why I did not like it.
I will say the return process was easy. If I were to knock the company, I would say they are a bit swamped. The order took about 6 weeks (which they said it would) and there was a little lag in the response to return it, but that is me being picky, more than a major issue. They were prompt with a refund, and they even sent an email to confirm.
If it works for you, then I would not hesitate. I would say the workmanship was good and the product fit and finish was quality, I wanted to re-holster with one hand while not accidentally racking the slide while re-holstering, so it did not work for me.
Well, I've been using my Alien Gear IWB for almost two months now. Conclusions - very durable, very comfortable - great value. I am finicky, but I would recommend this product.
