Many point to the Glock 19 fitting the bill, but I have that and a 17, and always opt for the 17 due to superior shooting characteristics. Perhaps counter-intuitively, I also find that it carries slightly more comfortably, due to spreading pressure against the skin over a slightly larger surface area, thus reducing pounds per square inch pressure. The 19 does, however, conceal slightly better, due to the slightly shorter butt frame, yielding two rounds less magazine capacity. The slide length difference means little in terms of concealability when carrying IWB, but it does represent a slight reduction in shootability for the 19 vs the 17 due to the shorter sight radius. The longer grip frame on the 17 is also superior for shooting vs the 19.
