This might work for you. I had a holster made of kydex (or some plastic) molded for me at a gun show for my Springfield XDE. I tried my TX22 in that holster and it fits really well. The XDE snicks into place when fully inserted. The TX22 does not fit that snugly, but it fits snugly enough that I can hold the holster upside down with the gun in it and it doesn't fall out. That's good enough for me. So if you haven't found something else yet, try one made for an XDE.
