Thanks for the link - Since this is an open nose holster the length doesn't make a difference. I think it should be very workable since it's Kydex. A heat gun can be used to loosen or tighten, and since the differences are in the order of a thousanth of an inch, I think it should work. Still I'll check with the mfg. Thanks!
If you are buying a new CrossBreed, they should be able to make one specifically for your pistol. If you already have one, the instructions that came with it tell you how to tighten or loosen retention. I used my wife's hair dryer to tighten retention on my PT-111 when I first got my CrossBreed.
