Well, I'm deciding on whether to get a G23. Got a 20s, 26,30,36. All are gen 3's. Is it logical to start another caliber? The 10mm is my woods gun and as you can see the rest are 9mm or .45acp. Like the idea of .40 and being able to convert the barrel to shoot 9mm. If I get the 23 it would be a Gen 4 FDE. Darn that Hickok 45 if making me consider another Glock. Heard nothing but good on the G23. What do you guy's think?
