I have had kydex holsters from Michigan Holster Co., X- concealment and now Black Rhino. The first holster from Black Rhino, the TCS, their version of the pancake holster, I ordered as is and I really like it. I've had it a little over a year, it is well made and pretty solid. The second one I requested them to leave open at the bottom and just below the muzzle with standard belt loops instead of the pancake wings. I like it so much that I asked them if they could cut down the first holster to be open on the bottom. They're reply was awsome, they are going to modify my existing holster at no charge and even sent a prepaid RMA and first class shipping.
I highly recommend them.
