I was waiting years. I like Glock, no issues with them, they work. I ain't holding my breath for a single stack 9mm. The two top choices for the composite lower and fairly decent are Springfield Armory and S & W M & P. The Springer has a little bit of rail and from what I feel weighs a bit more. I am going with the S & W Sheild in 9mm.
I looked hard at a Kahr too. But ultimately can't stand the trigger.
Oh - I believe Glock will come out with a single stack 9mm when it is profittable. In like another 5 years (that truly depends on politics as well) . Everything Glock does is driven by profit, which is as it should be for a business, but they want all the rewards and market when they jump in. I do respect the product. But, IMO, they missed the boat with the .380.
