Blade-Tech won't do any customized versions of their holsters. Believe me, I've tried. I have several of their holsters for my SIGs. If you want a custom kydex holster try out Skunkworks Concealment Solutions. I have a kydex shoulder rig for my P228. The quality and craftsmanship is top rate!

Or you can e-mail them at email@example.com. Give them a call. They work wonders. Tell them Adrian sent you.
