The 17L isn't much different than the 34, it's slightly longer bbl @ 6ish" compared to 5.3" of the G34, but it also has the same 4.5# trigger that the 34 has, and the same adjustable sights. The first generations of the 17L (I have 2) came with a lighter trigger disconnect, they were 3.5# back then, as were some of the original 34/35 triggers, and as Mav said, there are dozens of aftermarket trigger options that are easy peasy to install. The current stock 34 triggers are pretty decent at 4.5 though, so far as decent goes with a striker fired pistol that has a safety mech incorporated into its trigger.
The OP has said in previous thread's that he's tried out other pistols, and in this one he's asking specifically about the Glocks. Yes, there are many other options, but deciding on a Glock is never a poor choice, or the wrong one, millions of shooters use them, including all kinds of specialty units and competition shooters. I'm not sure why everyone is still offering opinions on other stuff - PPK for example, isn't even a 9mm pistol, it's s .380, and due to that plus very limited capacity, plus cost, makes it more of a backup CCW pistol or specialty item, then what the OP is looking for.
