The "sheath for 6" knives" is really easy to re-shape, the plastic inside is softer and molds at a lower temperature than kydex. I re-shaped mine to fit an SJTAC without about two minutes of work. It should be absolutely no problem to hit the insert with a hair dryer, squeeze, and have a perfect fit, for either the test team or mil overrun versions.

However, I thought I remembered putting my Regulator in the 6" sheath when it arrived, out of curiosity, and having the tip poking out past the plastic insert. I could be mistaken, it's been a while, and now that I've molded the insert to fit the SJTAC, the Regulator won't fit anymore to test it.

I'm curious what the differences will be on the regulator-specific sheath that's being offered.
