Thanks for all the feedback on my previous thread. Now I have narrowed it down to the G23 or G27, leaning towards the G23. But now I am not sure if I should get the less expensive Gen 3 or the Gen 4. The price difference is not that much, but I don't know enough about the differences to make an educated decision. I have done the research but I don't see enough of a difference to know which is better. This will be my first Glock, so I don't know enough about them to make this decision without some feedback from some more experienced folks.
