I "played" with my Sig220 Carry 45acp yesterday morning after a 16 station round of sporting clays. It had 150 rds through it when I acquired this pistol.
Here's a picture of the "220 carry" [ the one I fired was not two tone ], which is the commander sized gun to the full size 220. 3.9" barrel, 3/4" shorter in slide length, takes the same 8 rd mags as it's big brother 220 as the frame is the same as the 220 as well.
Included is a photo of what this gun can do at 10 yrds [ the minimum we could fire on this range today ]. Benched for groups initially with 20 rds, standing two handed rapid fire with Pistol Quick Kill [ about 4 rds a second ] for the next 130 rds produced that target.
That target was placed on the same cardboard backer as targets used previously by someone, a few of my 45's went just out of the black [ the low left ones ], the black dot I'm firing at was 8" in diameter.
Overall, the gun ran as expected. A few failures to feed the 8th rd out of the mag with practice ammo, but with the Ranger T 230 standard velocity I carry on the street, no hiccups whatsoever.
It's a nice gun, I know others have experiences they'd like to share with Sig 220's right?
