Cordura similar in quality to Bianchi\'s Accumold, quality snap, doesn\'t come undone accidentally. However, the M30 won\'t go all the way down with the regular crenellated tailcap, I had to unscrew the stainless steel ring from the bezel to be able to close the holster, but later ordered the smooth tailcap and it turned out to be a great fit. Do not buy if you don\'t have the smooth tailcap, it\'s gonna be a pain getting the light in & out. The only trade-off is that the light can no longer tail-stand with the smooth tailcap on. Will fit a 2.25\" duty belt no problem, the only drawback is that the loop on the holster is situated a little bit too high for my liking (an inch from the top) the holster sits quite low on the belt so it\'s gonna make your whole belt go up each time you sit in a car.
