Hey all, I bought a MarkV, frame marked New Detonics, Bellevue, Wa. Serial CR215xx and Detonics 45 on the left side of slide. I purchased this as a birthday gift for my dad to replace one he had stolen some years ago. It came with some really crappy pos grips. (Oversized with finger grooves dremeled out!) If anyone has an extra original wood set or Pachmayr's or anywhere to find some please let me know. (I've watched fleabay and gunbroke, no luck) Thanks for reading, and thanks to MGB for a great place to spend the afternoons!
