The Glock 23 is as far as I'm concerned the best of the Glocks, and one of the all time best duty weapons in L.E. . Best feel, best point ability, best carrying, and best in caliber. I prefer it over the 45acp, although a big fan of the 45acp. I definitely prefer it over any of the nines including the 357sig, aka 40cal brass necked to 9mm.
I have really resisted to buy a Glock 23, and I suppose it's due to laziness on my part as they have to be dealt with differently than most on concealed carry, which I mean, a holster is just about mandatory for safety of the carrier.
