my first handgun was a glock 17(9mm) and i picked up a Sig P220(.45ACP) about a year after that. i can honestly say my .45 Sig shoots smoother and straighter than my glock 9mm without a doubt. i plan on using it as my carry weapon once my chl arrives
I own a Sig P220 Match in .45acp and it will group as many rounds as you can send down range at 33yrs smaller than a 3" pattern.
I shot and cleaned a handfull of my pistols a few weeks ago and between the Colt Compact 1911, the 3 XD's, my SA 1911 and my Khar the Sig is the best shooting and easiest to take down and clean.
I would look at some reconditioned Sigs for a first before spending another $800+
I actually own 3 220's... A compact two tone, full frame stainless and a regular blued finish full frame. It's pretty neat sometimes I mix/match parts and have a carry model full stainless. They are all damn accurate but for some reason I can't shoot for shit these days. I used to do well but my groupings are getting larger....must be something with my grip.
Looking for sponsorships for 2010 on the car above... PM for details and schedule.
