Had a Sig 1911. If I had it to do over again I'd have looked at the Dan Wesson as a previous post recommended. Best bang for the buck from my researching.
For a home defense gun, FNX all day. More rounds in gun = more time in fight and home defense is a serious duty. Get the Tactical if you want to put a silencer on it in the future.
For a 1911 costing around a grand, SIG gets my vote: well-made and finished, accurate and reliable. But my first pick for home defense is the SIG Model 227.
Hope you enjoy the Kimber. You're gonna hear a lot of crap talk about their pistols. Ignore it. I have two TLEs (Custom & Ultra) and they've been great.
