which Muderlack book 1st?

[Dean Romig]

Muderlak's first book is nothing like Peter Johnson's. Muderlak's stands quite nicely on its own and even dispels some inaccuracies in Johnon's... not to disparage Johnson's at all - it was, after all, the very first book dedicated solely to the Parker gun and was the base upon which most works on Parkers published post 1968. You really owe it to yourself to get all the books on Parkers if you want to have everything in your library... And don't forget Larry Baer's two volumes.
