Well, it’s your money. I’d prefer the .357 Sig. It’s a bit more powerful than the .38 Super and is available in more guns. The only disadvantage is that you’d lose a round in mag capacity compared to the .38 Super.
Given a choice between a cocked and locked 1911 pointing at my body parts and a Sig 220, I’d take the Sig.
If your going to buy the 220, you might want to check and make sure the frame rails aren’t cracked. I don’t know if this happens with 220’s, but it was fairly common on the real old 226’s.
Simply remove the slide and look for lengthwise cracks along the rails near the where the ejection port is located. Typically, it’s a single crack on the right hand (ejection port side) rail running inside the top edge of the groove cut into the frame, maybe one-half to one inch in length. Cracks can be pretty hard to see.
(If you know what your doing, the easiest way to check for this is to remove the locking insert and look at the inside of the frame rails. However, locking inserts are tricky to fool with.)
The early 220’s came with heel mounted magazine releases. I assume the one you’re looking at has a side mounted magazine release (like a 1911), otherwise, its overpriced.
The old K-Kote was pretty lousy; but so was the blue. If this pistol is at 95%, it probably wasn’t used much.
Don’t get me wrong, the 220 is a great gun. I’d love to have one myself (though definitely in .45)!!
