Although the OP states:
I like the Glock reliability, I hate the trigger.
in the next ten posts three different posters recommend a Glock. Incredible.
I will try to make this a thoughtful post.
Yes, I have three Kahrs (PM9, P45, PM45). Trigger is long but exceptionally smooth and light. I have many rounds through the PM9, almost as many through the P45, and only a few through the PM45 (just got it). In the past three years the Kahrs have seen 75-80% of my carry time, which is every day.
I also have a Kimber alloy framed 3" 1911 (and have owned others). I shoot the 1911 better than anything, but the finish on the Kahrs rivals the Glocks' (yes, I've owned several). As much as I love the Kimbers, their finish is not as durable as the poly framed guns.
I have owned half a dozen HK P7s over the last 25+ years, and they are a great handgun, although only in 9mm--the .40s are large and unwieldy. Great trigger, quite accurate, and they are one of the great values these days. A $1200 pistol for ~$600. Downside? A tad heavy (all steel), the blued finish is not terribly durable, the ergos are "love 'em or hate 'em"...I love them.
Three very different choices...three very good choices in a single-stack.
