The G27 would probably be my choice of those, simply because I've used a a couple glocks (G19, G23) and found them to be nice to shoot. I don't like the glock in .40 very much from a results standpoint as I couldn't hit anything with it, which is a bit scary. I imagine that it was either the gun not being sighted properly or "user error". I had no trouble with an .45 ACP (M1911) or 9mm (G19), so I don't know what the deal was.
Have you considered a Sig? They make quality pistols like the P239 (available in 9mm, .357 SIG, and .40 S&W). It's only 6.6" long, which is barely 0.3" longer than the subcompact glocks. According to Wiki, "...the P239 has become quite popular in the United States as a concealed carry pistol."
