I bought one of the first 17s to hit this area. I hated it. Just couldn't get used to shooting it, though it shot "OK." Went to a 19, same thing. A 22, then a 23, a 21 and so on.
I've had every single model Glock imports except the 45 GAP models. Had several of them several times

.
About 15 years ago, I started to get serious about shooting the Glock and found it was very accurate, carried well, but a bit big for a guy who loves lightweight J-Frames, and, I really could shoot it well.
Have used a 35 for competition and did "OK" with it.
Now I am down to one, a 19 and it is the only 9mm I have. I love it, wouldn't part with it and use it as the Bedroom HD gun.
Took a while to fall in love with them and, in retrospect, I think it was the plastic and looks that turned me off and translated into lack of really good shooting.
Now, I like the looks and all business aspect of Glocks and wouldn't be without mine.
