My 9 is a Ruger SR9, I love the feel, the trigger is great, fit and finish is great and I have always lucked out with Ruger. For my 40, I was thinking M&P, XDM, Taurus 24/7 G2, Walther and / or a Steyr M40-1A. I am open to striker or hammer, would prefer it to be as ambidextrous as possible, as both my kids are lefties , and would prefer a lower bore axis. I personally don't like the looks of a Glock at all. Everything I have researched on the Sig 226, while it is a very popular in the 9, says the bore axis is one of the highest which helps produce a very snappy recoil in the 40. So hearing what people go through hopefully narrows it down a bit.
