Rex Delta was just released. 9mm, 15 + 1, same height as a Glock 19 but shorter, a wee bit thinner and even a bit lighter, $479 MSRP.

Other Rex pistols seem to have gotten very good reviews over the past few years and the early pieces on this one are positive, although so far they seem mostly to be of the “I’m here at SHOT show and here’s an exciting new gun” variety.
If this one pans out on reliability and as a shooter, though, lighter, shorter, thinner and cheaper than a G19 seems like a winning combination.
