This looks like a great deal. For those of us stuck in California there's also the Rock Island Armory (RIA) 1911's that can be found for $450 and up. The come in all sorts of flavors like GI, Tactical, Commander, etc.
OMG, lets not turn this into a discussion on best calibers for home defense. Even the EXPERTS argue on the subject.
Centerfiresystems has those Rock Islands for $419 on backorder, compact for $399 also on backorder. As long as it is on the list for Cali, they will ship to you according to the website. Other than the recent ammo price gouging, they have been pretty decent to deal with.
