The ProArms Podcast - John Strayer's Blue Flame XDM

I want flames on MY slide!

Who did that paint job?

Update: It was the Springfield Custom Shop!
It's what they call Xtremeflauge finish, which is Armory Kote finish applied by hand by one of their gunsmiths. They can do it in various colors.  Each one is a unique design because each is hand done.
It's not cheap, either :-)
