uber,
I reread the review and recall him not knowing the difference either. Don’t quote me on that. There’s no markings on the cartridge body saying MkII. The Shelter had always been highly rated in the mags, always wanted to try one. Got a DEAL so we will see. From what the dealer said it came from an estate with almost no hours, so I'm expecting break-in time. (Weinhart Designs) You gotta trust someone, sometime.
