I just got back this afternoon from 90 minutes at the range with my new Cougar 8045. What a great feeling and shooting gun. The instinctive pointing of the gun is excellent--you can get good solid 10 yard hits just by practically waving the pistol at the target. It sits low in your hand and the trigger is crisp.
I tried a variety of ammos including Silvertip 185gr Winchesters, Hydroshock 185gr, Magtech 230FMJ, and Wincleans. All but the Wincleans offered excellent performance with the Silvertips producing the tightest groups. I have to admit, the groups weren't as tight as they were with the other gun I brought along (CZ75B 9mm), but the holes were certainly much bigger!
Not having owned a .45 before, I brought the 9mm along so I'd have something to compare the recoil of the Beretta to. The Cougar's recoil was only slightly greater than the CZ; I'd compare it to a .40cal Ruger P94 that I used to own.
In over 150 rounds with a brand spankin' new gun, there was not a single a jam or failure to fire. The Silvertip's grouped at a little over a couple inches at 10 yards, the Hydroshocks were about 3.5", and the Magtech's were about the same. The Wincleans were all over the place. I expect that my lack of experience with either the gun or the caliber probably account for the big group's and that they'll get much better in time.
I've never shot a 220 although I've shot various other Sigs in 9mm and 40 cal and know that they're wonderful guns; however, the Beretta's curved backstrap and instinctive point and shoot capability are better than any Sig I've shot.
My favorite test with any carry gun is to just pick it up off of the bench in front of me and squeeze off two rounds without aiming through the sights. The Beretta did as good or better than any gun I've ever shot; every shot found center torso on the silhouette and generally speaking they were pretty close together.
Big holes delivered center torso without taking time to do more than point and shoot--I believe that's all you can ask for in a carry gun. If that's what you're looking for, the 220 can't deliver much better performance than the gun I shot today...
