The Sig P220 is an excellent weapon. I've owned one for years now, and I've found it to be superb. I carried it daily off and on for nearly 10 years.
Sig own interesting, albiet biased publication cites examples of the SIG P220 firing 5 shots in 7/8" group at 25yds from a Ransom Rest.
The only cons of the SIG P220, as I see it, are the potentially fragile aluminum frame and the less than perfect trigger from the box. However, I've had my trigger lightly smoothed and I've never seen a SIG frame fail. Also, I installed Novak's low mounts with Trijicon tritium inserts.
Rent one at a range, run it through the paces and decide for yourself. You will not be disappointed if you buy the SIG 220.
