I've never understood the desirability of the P7. I don't have much information about it and was hoping you guys could fill me in on what makes it so fantastic. I understand the squeeze cock bit and I can understand it's value as a collectable as it appears they're no longer imported. But what makes it great as a firearm? And how large is it? Barrel Size is 4in but I've never seen one in person so the pictures may be deceiving. What would you compare it to size-wise - and lastly, how much do they go for? Thanks.
