I don't understand your hate for one of the highest quality handgun manufacturers in the world
What do you figure is the total number of SIG 1911s in circulation?
Yes, they are new to this game.
If you are unfamiliar with the 2005 on slide (maybe collapse is a better term) of SIG's QC that's not an indication it hasn't happened...
Did you not notice them trying to sue the BATF et al for placing too high a standard on "reliability" in their recent competition (I believe the largest gov't handgun contract...ever) which resulted in the SIG entrant getting tossed? Both the S&W and the Glock had no problems meeting the standard...
SIG was once a great manufacturer. Unfortunately they have really, really slid and if you don't know that, that doesn't mean it isn't true. Or does their slow march out of machined bar stock for small parts and into cast not seem meaningful? Have a look at some of the small parts they use these days...you will see casting lines on them! SIG Sauer would never have done that...that is SIG USA. Or the junk chinese red dots they stamp their name on...or the 556 with its famously wobbly furniture...
You might get a good SIG 1911...you might get a junk one. They don't QC their stuff like they used to...they don't use the parts that they used to...they don't have the staff that they used to...
It's a gamble.
To the OP - sorry for the hijack. Your best bet is the Colt or a Springfield Loaded, and after that I would probably look at the STI offerings. The Colts still use bar stock for pretty much all the small parts and the machining quality is high but they do tend to be pretty ruthless on machining sharp edges and just leaving them there.
Kimber is the company that gave birth to Ron Cohen, the guy currently killing SIG. Their rep for QC leaves a lot to be desired as well. Lots of features on a cheapish gun...that might be a good thing or it might be a red flag if you take my meaning...
