Jay, Making a choice between the Kimber Micro 9 and the Sig P938 is a bit of a doozy. It's basically the same gun. The specs are virtually identical. Operation is identical. Both are widely held to be fairly easy to shoot despite the short barrel and small size, which has always made shooting pocket guns a tad rough. Both are very easily concealed and carried. A Sig P938 holster makes the pistol positively disappear, same with the Kimber. Part of it comes down to you. Believe it or not, the micro 1911s can be fairly comfortable and fill the hand more than you might think. Handle them both at a gun store some time, see if you can shoot both. The one that feels better and/or that you're more accurate with is the one to acquire.

Kimber!

Jay, these two are virtually clones in feature and function. In my opinion the Trigger is much cleaner in pull and break which should yield slightly better accuracy on the Kimber Micro Nine Sir. Either would do the intended job though.
