Okay, first of all, I believe about 1/2 or more of my 12 gram is being lost on peircing the 12 gram, because then it sputters for a while till the hammer catches on the sear. So, aside from that, I'm only getting 4-8 shots after that. Is that normal? I put a cooper-t Imp kit on a palmerized P68. What options do I have now as to what I do for air supply? Do you just turn the screw w/ a screw driver in the back to adjust velocity? Also, it appears that my IMP kit will only take automag frames. Is that normal on some? I see the one on the PGP in the gallery, and it has the normal sheridan frame. I can take the grip frame off (appears to be automag looking like.....has Smart Parts wood grips on it) but the trigger/sear and springs stay in the bottom of the imp kit. How would I put my original sheridan frame on there? Is it possible to put this automag-cyborg thing onto just a normal sheridan w/o the Imp kit? ANY help is appreciated. THANKS!
