Thanks to all who have inputted to this. It's very helpgful. But Benjiboy, yours was the answer I was looking for! I assume it will be OK in the 45 CL-4 and allow me to just stuff it full of 6 x AA Duracell batteries and shoot away? Some others have stated about power variances? Is yours OK using it like that?

I'd certainly prefer this solution because then I can just buy a massive box of batteries and know that I have plenty of pwower when I need it without owrrying about lag or poor performing worn out batteries.
