It seems that one important question is missing from the "better/best" criteria.
How does it feel? How well does it suit you...personally...when you pick it up?
An important consideration, because...like it/believe it or not...this will have an effect on your performance. Maybe the most important consideration of all.
Not what you can adapt to. Not what you can eventually get used to.
How does it feel? How does it fall into your hand?
Cooper once wrote: "A proper weapon should be alluring to the hand."
A wise, old gunman once told me of selecting a revolver: "You'll know it when you put it in your hand. It will simply hit the spot."
No Glock I've ever handled has hit the spot. In fairness, neither have many of the modern offerings, but since this thread is focused on the Glock...
This is not to disparage. Many people like them. I'm just not one of those people. I've tried them. Several of them. I can't get my hand to wrap around one to save me outta torment.
Plus, I knew way back in the early 80s that trigger widget was gonna be a problem on reholstering if one's attention lapses for a split second, which is easy to do under stress or even in a relaxed hurry...but that's a different question for a different day.
My 2% of a buck. No more, no less.
Cheers!
