I actually just sold my P220 Elite 10mm. Nice gun, but I prefer the 1911.
The Colt Deltas tend to be very reliable, and less fussy about mags & ammo than other guns. They do not have fully supported chambers so the heaviest loads are risky. I've owned 4 of them over the years.
The Kimbers do have fully supported chambers. They also have MIM parts and will likely need some tuning to correct fussy feeding.
The DW's are better made, and have better sights IMO - the Silverback is a real neat design - it borrows a lot of styling tips from Nighthawk. I agree the Silverback is a neat choice...The Nighthawks are more highly finished, and arguably are the best of them all.
