That's quite a back up gun...
I like these folks:
High Noon Holsters
Milt Sparks Holsters
El Paso Saddlery
I have an outstanding order with:
CrossBreed Holsters, Innovative holsters for concealed carry-1911-Glock-HK-Sig-Taurus-Kimber-Springfield-Colt-XD
I've heard nothing but good things about crossbreed so I'm looking forward to receiving my order.
Highnoon doesn't have much that would work as a good cross-draw, and I think you'd need to talk to crossbreed about your needs.
