Interesting find, Thumper!
I'm thinking that this might work for a G26 owner who wants to pocket carry?
I'd still worry about a pen getting shoved up the barrel, and other junk wandering into nooks and crannys that shouldn't have junk in them.
A friend of mine insists on pocket-carrying a (no holster) G27 in his sweat pants. Maybe I'll just order him one...
