I have both the 220 and the 8045. The P220 was the first Sig I bought, and it was also the gun that addicted both myself and my father to Sigs. The second Sig I bought was another P220, and I just love the way the 220 handles: well balanced, smooth trigger, very managable recoil, reliable, accurate. Buy the P220, you won't go wrong. I bought the Cougar 8045 in the CatPak recently, and haven't had a chance to take it to the range yet, but I hope it becomes one of my carry pieces after I put a few hundred rounds through it.My father has the Cougar 8040, and it's a sweet piece of hardware and I love the rotating barrel method of managing recoil. If you're looking for a carry piece in .45acp, look hard at the Cougar. If you want a fun range piece, the P220's the ticket..Dan in GA
