you'd be hard pressed to beat a G23. they are stellar guns. I especially love my gen 5. finger grooves on that size glock don't work well with my gorilla hands. but that is just me.
hickok has since abandoned the .40. you must have seen one of his older videos where he discussed it and mentioned carrying it as a reserve officer. he is all aboard the 9 train these days. but, he, like all of us, are getting older every day. I am a die hard .40 fanboy but I'd be lying if I said the 9 wasn't easier and more manageable a caliber to shoot. don't mean I like 9 better. hands down, if I could only own one caliber it'd be .40SW.
