I love my 1911 Para Commander, the Tac-S with it's LDA trigger. Great gun. Sadly, though, I need to agree with Ichiban.
Right before they moved to NC, I ordered spare mags from the website. After some time (weeks), no mags. I called NC, and was told that was handled out of the office in FL. I called FL - got an answering machine. Series of shenanigans, calls not returned, computer was down, etc., and some weeks later, still no mags. Got the excuse at one point about "Golly we moved. It'll get sent real soon now".
I think it was ca. 3 months before the mags just showed up.
Sig hasn't been much better, sadly. I ordered a .22 conversion kit for my P220 back at the end of November. It was on a good sale, something like $100 off. Got 2 extra mags too. Trouble is, I was told that the slide was back ordered and it would be a few weeks. No problem. Early January I called and was told they were in and would ship that week. Two weeks later - nothing. Called again and was told the credit card I gave was invalid. BS - gave them the same one again, and got the kit late last week - nearly 2 months after I ordered it.
