Great little guns! BUT<<<
Based on the example I handled Thursday evening, a 4" adjustable sight model, I'd recommend going over an ordered one (Trailside) with a fine tooth comb before accepting it. The one I saw was nothing short of junk. Mismatched grips, failed to go into battery, magazine would not eject, were the most obvious defects. I have to wonder if these aren't being rushed out of the factory to meet demand. I almost doubt that it was capable of firing at all, let alone firing the supplied test target. For $400.00, I demand a better product than that, and am surprised that SIG would risk their reputation with something like this.
The 6 inch fixed sight model was excellent however, in fit, finish and function, so it's obvious that they do make good ones. More people report good things about them than bad also.
I can see one in my future, since they are great looking/feeling little guns. The kinda round shaped grip reminds me a lot of my High Standard in the way it feels.
