I have a G23 gen 4in 40 caliber. I am trying to decide whether to buy a .357 sig conversion barrel for a couple hundred bucks. Local Glock armorer confirmed to me that the one for the G23 (a G32 barrel) will function in the G23. It'd be nice to basically get two guns for the cost of one barrel. My question is: should I even bother? Tell me why I should or shouldn't make the move to .357sig. Who thinks the .357 is better? Who thinks it's a waste?
