Hello ColdHit and Others.
I too am having difficulty separating the grenade section from the body. I recently received an empty hilt for a self-install. I requested no glue but they glued them anyway. I was able to break free the lower section of the body no problem but the grenade section is a beast. I even tried a heat gun for about 5 minutes but all it did was make the hilt almost too hot to handle.
Upon looking at it closer and comparing it to pictures of older versions I've noticed the bottom black portion of the grenade section is now thicker. This is leading me to wonder if they've changed their manufacturing process and the grenade and upper body (switch) is now one piece.
If these are now one piece it will really be a bummer as i'm trying to make a shoto companion using the body as the base. With the ASP version of the body is longer than the original Exhalted/Fury body i've got to rethink my plan. FYI, I was planing on swapping the Exhalted and ASP Fury bodies. Here's the ASP "Exhalted Shoto" I was going for:

I've got an email into customer service to see if they can shed any light on this, so I'll report back once I get a reply hopefully later next week.
