I LOVE my Glock 23! Its my EDC and is what I recently taught my fiancee how to shoot with.

While I don't have comparisons for longer range shots in other calibers, I recently had to take a recertification/refresher course for my CCL (stupid NM law) and my instructor asked if I had done any long range shooting with my Glock 23. I hadn't, so he took me out to 50yds with a paper target and had me take my time shooting through a full mag. When we went to check out the target up close, I was shocked to see how tightly grouped they were, if I recall they were all within a 4-6" diameter circle. Granted, they weren't in the center of the target, they were to the left of the target which could be accounted for by either the wind (blowing at me from my right) or from my sights not being properly dialed in. All I can say is that my G23 is more accurate than I had expected and it was kind of a thrill to shoot at 50yds for accuracy, I might have to take it out to 75yds and see how I can do (and compare it with a 9mm conversion barrel).

Regarding recoil, I love the recoil of .40s&w. When I shot my BIL's RIA 1911, the recoil was much more than I was expecting and completely different. Not painful so much as difficult for me to control and get quick follow up shots. With my Glock 23 I can easily empty a mag on a target without having to recover from the recoil after each shot.
