Is the hammer weight in the Maverick Slug Power Kit too wide?

I installed the Maverick Slug Power kit 

The heavy hammer that comes with the slug power kit seems to be too wide to float freely inside the hammer.

I installed my heavy hammer weight without removing the hammer itself and over hundreds of shots the hammer weight is stuck fast inside the hammer. I can't remove it—totally stuck.

I'm wondering if this is a defective hammer weight—OR could it be misalignment—the hammer being weight going forward slightly off center and getting stuck that way. As far as I can tell it seemed to slide into the hammer when I installed it, but can't be sure. It could also be that I had a defective hammer from the start.

This photo shows it is absolutely wedged tight into the hammer
