I guess I'll tell my story:
I wanted to hate Glock. I really did. They were too clichéd... too much "fanboyism" surrounding them. My first handgun was a Walther P99. My second was a Walther P22. My third was an HK USP variant 1. All three of those were within a week of each other.
I love shooting all of them. The P99 is a little snappy but is a great gun with a lot of features. I love my P22 also. The USP is pretty neat. Fits my hand nicely and is a joy to shoot.
I went on those three for the first few months. I met up with a family member on a trip to the range one day. He was sporting his brand spankin' new Glock 17. He ventilated a couple of targets and asked me if I'd like to try. I didn't want to like Glocks but having never fired one, I at least wanted to try it.
Now bear in mind... this is a completely stock G17 with night sights. (He's a cop so wanted to get as close to the issued G22 as possible.) The stock G17 has a 5.5lb trigger pull and stock springs.
We put the target, an OPC (Ontario Police College) standard issue silhouette target, at 21 feet - again... a standard training distance and I loaded up a 10 round mag. (Damn thumbs - I need pinned mags!)
My first time ever shooting a Glock... I fired at a rate of roughly 1 round per second and put all 10 rounds in centre mass. 8 of them were in a 1.5" group, the ninth was within 2" and the tenth was a flier at 3.5". I was in awe.
I loaded up another mag and did basically the same thing with head shots. I kept that target and have it pinned on my reloading room wall to this day.
I went home that night and ordered a G17 and it has been my main competition gun since then. I've modded mine a fair bit. Extended controls, 3.5lb connector, Glockmeister spring, guide rod laser (just for fun!), Williams FireSights, grip tape and a few other things. I just love it.
Here's a pic of that target. The main group in the middle is 1.5" across.
