Will it work as "dual fuel" in the pistol, as it does in the rifle?

Curious....

the P'rod valve I can say that on co2 that gun will probably shoot real slow. The valve volume is small as compared to say a Disco valve and there isn't much room to open it up. If you want to try it you might pick up a bit of performance by opening up the trans port to .150" or as big as the trans hole in the barrel. The P'rod and the 1701P both use the same valve and from my prospective it's designed around being an air miser and not for flowing much co2.

I mostly agree, but I would stop at 0.111" so that it's still good for HPA (based on the various transfer port experiments that I've seen).

EDIT: I wrote 0.120" but after quickly reviewing a transfer port experiment result, it didn't look as good as the 0.111" or 0.101" for HPA. For comparison, stock is 0.080" I believe.

how it works. I've found .22's on co2 like as large a TP as possible without having feed problems. If you get it working right your shot count over the hpa will be a big bonus.
