Yes it is...I love the lock feature of the P67. This is just hands down my favorite mod of all time.I hardly ever lock my Grands. I do however lock my P67s, if I'm pocketing them, because the button touch is so light. I like the internal lock better than the lock on the Woodvils. One of my Woodvils has a particularly loosely turning button, and I have inadvertently locked it on occasion while vaping. It is annoying when it happens.
