Thanks guys -
I have the XDs 45 and a XD9 Mod2, but was thinking it would be handy to have a single stack 9, if I have some extra $ at some point.
I looked at the Sig P938 as well, smaller still and easy to conceal. I'm guessing the XDs 9 might be a better shooter than the P938 due to a bit larger and more specifically more weight. And the XDs 9 is about $230 cheaper than the P938 near me ....
