The 23 handles handles exceptionally well. Some say its too snappy, but I've never felt that way. I have heard many Internet rumors that the .40 cal Glocks have had some issues, especially when a tac light is attached. When a light is too tight on the frame it messed with the natural flex of the gun, causing FTEs (supposedly... I've never had an issue with a TLR 1 on my Gen 3 23)
Of course there's always the rumor of the Glock "kaboom", and every time I hear it I ask the person: did this happen to you? The answer is always "my buddy old me about it happening to his friend" or "a guy at the range says he sees it happen all the time." Etc.
The only time you can have too much ammunition is if you're swimming or on fire!
Gun stores: Where the morbidly obese can pretend to be mercenaries, allude to past experiences in Special Ops, and overuse words like "tactical" and "piece of kit".
