Thanks for the replies guys. I have been using a 2.0 ohm HH.357 for almost a month on my grand. The other day I figured I might as well try the 1.5 ohm HH that I have. So I screwed it on and in hindsight I should have realized that it didn't just screw in that easily - there was a tiny amount of resistance that usually isn't there. With the door opened I gave it a test fire and I didn't hear that normal sizzle of the atty - Next thing I know I can see a bit of smoke from the top of the battery and I see the spring begin to collapse. Thats when I knocked the battery out. Since I was using an IMR at the time the spring didn't even need to collapse all the way before contact was broken. Had I been using the 2600mAh battery it'd probably be a different story.
So I don't think there was any other damage to the mod and while I'd love to send it back for a checkup I don't wanna be without my Reo. I carefully pulled up the spring and changed the atty and now she's back in use albeit with an EM LR 510 but not a HH. I sent my HH back to Avid and I do hope they replace it bec it was definitely an issue with the threading.
