Hello NWFA, To my surprise, when I went to put on my Crossbreed holster a few days ago, I noticed a few small cracks in the kydex. I took the photo below. After that I wore the holster the rest of the weekend and the crack continued growing until it completely broke away from the top rivet. Just return it, right? The problem is I purchased it off Crossbreedseconds.com. At the time I purchased, I swore they came with the same Manufacture Warranty as the new models. It applied only to manufacturing defects and I'm not certain this qualifies. Does kydex weaken with age? Are there varying thicknesses of kydex within the different models? Mine is the mini tuck version. Yes, I've owned this holster for a few years. My disappointment lies in the fact that the holster has been used only on the rarest occasions. By occasionally, I mean 0-5 times per month as I find OWB to be the most comfortable for me. I loved this product. It was by far the most comfortable IWB holster I've used and I've told a lot of people about it at the local range, the guys at competition as well as on the forums... now I'm afraid I'm second guessing myself. Has anyone else encountered cracking issues with the Crossbreed holsters? I'll contact Crossbreed and follow up, but for now I find myself in the market for a new IWB holster. I'm certain mine is no longer safe for use.
