I think you mean Volquartsen. It's a shame what people believe and who tells them the stuff they believe. The who is the biggest shame sometimes. :shock:
I really like my VolquartsEn set in my MKIII 22/45. I used the MKII parts plus a MKII hammer bushing to rid myself of the mag safety without buying a trick of the month part. The MKII parts were cheaper at my time of purchase anyway.
