Another 1+ for both the Ruger SR9c (double-stack, 10rd primary mag, 17rd extended mag, 3.5" barrel, extremely accurate, very shootable, definitely concealable... I do) or the Springfield XD-S 9mm (7rd flush mag, 9rd extended mags available, 3.3" barrel with new 4" option coming soon, accurate, shoots well, and even more concealable). Had the XD-S, but no I longer. Found options that fit me better and felt better (SR9c included).
For you, specifically, both have ambi mag releases by default, and the safety on the SR9c is also an ambi. Slide releases are one-sided only (left side of slide). Lots of posts here about both guns, but feel free to PM me if you want to chat more about it.
