The current 220s have been re-designed since Browning brought those early ones in. Different rebounding hammer safety system, different recoil spring.
In '82 I bought one of the SIG-marked 220s, my department was the second in my state to authorize them for private purchase duty use.
Carried it for two years.
Two fellow firearms instructors (our three 220s were the highest mileage SIGs at that point) developed problems with theirs. One developed hammer follow, the other broke a locking block.
I sold mine shortly after, lost faith in it, did not want to wait till it broke down on me on the job.
If I wanted to shoot a 220 much, or use one for defense, it'd be a much more recent one.
That's not dumping on SIG, I've worked with current 220 variations & own two 229s. You'll probably get other positive comments, I'm just passing on my own impressions.
I certainly would not take out a 22% loan to buy an old one.

Forgot to mention the mags.
The ones we got in the '82 time frame had the older zig-zag seam weld at the rear of the magazine. Those tended to crack up near the top of the seam weld.
220 mags have long since been "re-engineered".
The original 220s were interesting developments, but did have their weaknesses.
