Ok so I have an older model Blade-tech paddle holster. Non injection molded. I love it...great for easy on and off when I need it for work for my duty Glock 23. Adjustable tension screws, love it. It is an older model that looks like the whole thing paddle and all was formed one one sheet of kydex. It does not see adverse temperatures or changes or abuse. However today I went to put it on and the paddle had a lttle too much give to it. I checked and the underside of the paddle has a stress fracture starting, but not all the way through. I obviously cannot use this holster anymore, for safety purposes. I looked on their website, and no mention of warranty.
ETA: I called right after typing this and the very nice lady on the end of the phone stated that it was covered under warranty, and would be sending out a new one to replace it, all in less than five minutes....great comapny to deal with.
