Ok, if you like everything else about a glock but the trigger, why not change the trigger? For $20-30 shipped you can change the trigger to almost anything that suits your taste. Want a more dao? Want a heavier or lighter pull (3-12#)? Want a smooth face or even metal trigger? It is all out there and for dirt cheap.
All that said I have two single stacks at the moment that I fully trust as they have been through better than several hundred rounds each without a single failure: a Feg AP9 and a Keltec PF9. The PF9 falls under your length requirements. The Feg has been ridiculoisly impressive to me. Feeds anything, accurate, fairly light weight. The bad is that it can bite, grip depending, and the stock trigger sucked. I put in an 11# spring from wolff for about ten bucks and it now has a better trigger than my ppk/s. The sights suck compared to the walther however. Is it my carry gun? Nope it is my truck gun. For $167 + $12 in springs, it is a great, reliable value.
PPS seem to have the bugs worked out fyi and they are worth a look. Good luck!
