I'm looking to grab a thigh holster for my M&P9 w/ x300. Bladetech and Safariland both off a holster that suits my request however the Safariland holster is uber expensive so I'm looking at the Bladetech. Since my M&P has a threaded barrel, I'm curious if the bottom of the holster is open and would be able to accomodate the extra barrel length. I imagine that it is but I don't want to go through the buying process if it happens to be enclosed and causes a holstering issue.
