I know they are different calibers, but they are the two pistols I've narrowed my search down to... I currently have a G23, and I'm looking for something smaller to carry. LGS has both a G27 Gen 3, and a black XDs in stock. Price is only $30 different, in favor of the Springfield. I love my Glock, but I'm really attracted to the slimness of the XDs... Any recommendations?
