Hey, I appreciate passive aggressive dickery as much as the next guy, but that is literally all the press release said:
"Guitarist Jake Langley has parted ways with Handguns. The departure was mutual and amicable. Handguns will still be taking part on their upcoming tour with Set It Off supporting their brand new record Angst, out now on Pure Noise Records. "
Neither their Facebook nor their Twitter make any mention of it, so until there's a statement release, that's all we have.
