Go with the smith 1911, its a way btter pistol than the p220
My SIG p220st is the least reliable firearm I have ever owned, the extractor failed right out of the box, its an extremely poor design for an extractor, its prone to failure. When I called SIG I waited on the phone for 45 minutes each time took five calls to get their attention the first three they told me jamming on everyother round was normal and it just needed a breakin. The 5th call being to the president of the company. They fixed it for now but I notice it still moves in the slide so it will go south again.
I own 6 1911 pistols, rangeing from a stock Colt govt. model made in 1978 with about 10,000 rounds fired by me, unknown how many by the previuos owner, .two kimbers, I have over 15,000 rounds out of my series one kimber custom classic target, and 7000 out of my TLE II with ZERO, ZERO, failures of any kind.
I only have one expensive P220 and its failed about 250 times out of the first 500 rounds, sig kept telling me it was fine and just needed a break in.
I have also read on the sig forum of several others who had my problem with a new p220, others claim that they only have the extractor break or the trigger bar break every 2500-5000 rounds, and at 5000 rounds every SIG needs a rebuild.
1911's are just getting broken in at 5000 rounds
JMHO YMMV
