I'm considered an "old fart" when it comes too knowing 'bout the SIG P220;
no expert, just an old fart as I've owned one for many years. I purchased
my first West German SIG-SAUER .45 caliber P220A in July of 1988; selling
it off around '91 or so to a fellow LEO. On March 31st, 1995 I acquired my
current West German .45 caliber SIG-SAUER P220A. Both, served me very
faithfully during my tour of duty.
I tried too like Glock's, but they NEVER fit me well; always returning to the
SIG P220A. As a matter of fact, I liked it so well that I added a West
German 9m/m P228 too my collection. Both firearms remain on inventory as
we speak~!
