Thanks McTrucky
Some great advice. No, the picture is a stock from Google, not the actual pistol that I will be having.
The one I will have has the two "Star Trek" rods to the rear but no front balancing weight and I think the front sight is presently set as far forward as it will go.
The guy selling it did mention batteries and the need to make sure its switched off after use or it will drain quickly, so once again, great advice.
As I recall, the trigger is already set with a positive feel, though that actually is extremely light (in comparison to my rifles!), but I will have a play about to see what suits.
Of course, I will get some pictures up as soon as I have it..
Thanks again
