So I purchased a NIB G17 about 3 months ago. Long story short, my dad loves it but I don't like how I have to shift my grip to drop a mag or release the slide. I'm giving the 17 to my dad and he is going to get me a glock that fits me better. I think I want to do the 19 or the 23, both of which I have heard great things about. What I'm really looking for is your personal opinion, realizing that it is simply that. 19 or 23? If I got the 23 I would most likely shoot 9mm 90% of the time and I'm worried that having the interchangeable barrels and magazines would decrease its reliability. That being said, I like the idea of having the ability to load .40 (or even 357 sig) if I choose. I've also heard fewer complaints about problems with the gen 4 23 compared to the gen 4 19.Thoughts?
