No, not custom. Back in the day they offered these as Ruger Mark II pistols from the factory. Now, with the Ruger Mark IV, they have the heavy tapered 10-inch barrel as an offering once again, but this time, all Mark IV pistol uppers are interchangeable.Love those long barrels. Are those custom? I wonder if anyone ever made one with an extra long tapered barrel to make it look like the Luger artillery model. That would be cool! (And before anyone asks, I am aware of the erma .22 Luger clone, I had one and will never have one again ha ha! Man I hated that pistol).
