Quite a long time ago, I had a 9mm Sig P226 and a .45 Sig P220A, both made W. Germany. I shot both of them quite a bit for about three years but found that they had become Safe Queens in deference to my Cz75, Cz Clones, and other 9mm and .45 handguns. The P226 was sold off during the Clinton AWB period, along with 5 pre-ban Magazines, brought more than I had paid for it.
The .45 P220A was sold to a retired Police Officer who had carried one before and wanted mine very badly. He made a very generous offer for it and the sale was done!
During my ownership of them, I did not like the high bore axis of both, and the P220A was very picky about Hollowpoints and Semi-Wadcutters.
Also, the P220A, back then, was quite undersprung for a .45 with only a 14 lb Recoil Spring. Current P220's use a 20 lb Recoil Spring.
I had gone to a 16 lb Recoil Spring which made it's operation, more tolerable, but I still was never really happy with it.
I have no regrets about having sold them, unlike some other Firearms I actually do miss.
