I got the 17L as a project to do mods on.
The stock trigger is horrible - but I find all stock Glock triggers to be unacceptable to me. I have a G34 that I bought used that came with a Sotelo trigger kit. I swapped my Sotelo trigger kit to the 17L and it's a lot nicer. I went to the range yesterday and had some fun, I created a shot group at 25' that I was happy with. Firing standing, two handed slow fire I made 1.125" shot group with 5 rounds.
It points naturally for me, has hardly any felt recoil. It's very easy to bring back on target and I was surprised at how accurately I can fire it rapid fire. I did some one handed rapid fire work with it at 10' and putt all the rounds in a 2" circle.
I've never had any problem with this pistol so far - no feeding or FTEs.
It is a lot easier to cycle the slide than my HK P7M8, but like I said, I've never had a failure to feed. I've also taken it to the range totally gooped up with grease - way way over lubricated, to the point where on the first shot, greas splattered on my shooting hand, but I've never had the slide fail to cycle.
I can't figure out how to post pics on this forum or I'd show you how much grease I had on it...
