This is such an oddity for a first post, especially from one who only registered but 6 minutes ago, I really must question the legiitmacy of such a question, even as we see your posts over on a knife forum asking the identical question, and indicating you would like such a knife to "complement your desert eagle".
I would like to suggest you take the time to read the numerous posts in this subforum (rather than just blindly posting in every knife related forum you find) and you will rapidly come to the conclusion that nearly all of us here are interested in historically correct knives, or "Old Timey" knives.
Further, If I might humbly direct your attention to the two stickies at the head of this subforum, especially " On To Other Business... " you will clearly see the intent of this subforum.
Such a thing as a "pistol grip" knife really is an oddity, and frankly [ no offense :-) ] in this scribblers humble opinion, an ugly obomination that would not fit into the "Cowboy Action Shooting" game that this is all about-
