Basically, you want a gas operated bolt gun, from there it is a matter of personal preference and gun fit.I had a super black eagle 2. Like the gun but hated the trigger bite on my finger. Was using black cloud 3.5. Sold that gun and I'm now shooting the beretta A400 kick off. Gun shoots 3.5 but I fell in love with black cloud #3, 3 inch. Looking for a gun that will shoot 3.5 if I needed but mainly I will shoot 3 inch. Who likes what. Was looking a Super Vinci. Don't want the finger bite and would like a soft recoil. Thanks
