GregSy, there's a great old Jim Croce song that has these lyrics in it:

You don't tug on Superman's cape
You don't spit into the wind
You don't pull the mask of the old Lone Ranger
You don't mess around with Jim

I think in this case you are pretty much spittin' into the wind and tuggin' on Superman's cape. When it comes to Parker guns, EDM pretty much has the goods. Change that last line to read "you don't mess around with Ed."
