I have the 14 inch 45/410, in a G2 Contender. I find recoil very mild and pattern reasonable at 25 yards, or less. I have not tried slugs, but would just prefer using 45 Colt, if the need arises. The only thing I do not like about the 14 inch Contender barrel, is that silly looking vented rib. I much prefer the looks of the 15 inch Encore solid rib.
