My experience.
I used to REALLY REALLY REALLY dislike Glocks when I first began shooting.
My reasons were:
1) The triggers were difficult to get used to. Too much staging and very mushy.
2) The grip angle caused the gun to point upwards
3) The finger grooves drove me nuts
4) The fullsize Glocks had fingergrooves that were too far spaced compared to the compacts
5) The subcompact Glocks only have two finger grooves so that my pinky would hang off of the gun
6) The sights sucked
7) It has a polymer frame
8) No external safety (I was used to the 1911)
9) Since I'm a die hard 1911 fan, all those 1911 vs. Glock threads drove me nuts.
10) I like my guns to have some weight to them
11) It felt cheap.
12) You can see light from one side of the Glock through the other side.
Needless to say I was pretty biased against the Glock pistol. But reviews after reviews I was becoming oddly interested in the pistol. So I took a look at a compact Glock one day and even rented a Glock 23 to try it out at the range. I remember distinctly renting a G17 long time ago and I absolutely hated it. But that was because we also had a Sig Sauer P226 and to me and my friends the Sig felt significantly better. Anyways, back to shooting the G23, it felt good, and I wanted to fill a .40S&W niche.
I ended up buying a G23 to try out. I've gotten used to the pistol. The compacts G19/23/32 frame feels good to me. It fits my hand well, but I cant overcome the pistol pointing upwards to what feels good to me. It just doesn't point naturally. I tried to install a 3.5# connector by Schere and it doesn't really help the trigger any. It still sucks. I tried the $0.25 trigger job. I guess its just practice practice practice, but I dunno... While I'm fond of the Glock 23 (Easy to use, disassemble, lightweight and reliable) im equally not fond of the gun for most of the reasons I've listed above.
But each day I'm still opening up to it. I haven't sold my Glock yet.
