What sucks about the 45 acp to me is that handguns that use double stack mag are too thick/fat in the grip for my hand and that the factory ammo is about 50% more than 9mm. Handloading the 45 acp helps mitigate the cost some but 9mm is still cheaper.
I like that the 9mm can have high capacity due to their double stack mags and still have a reasonably grip thickness. Compound this with cheap & economical to shoot, shines favorably on the 9mm.
From what I read and pulling out of the gun mag, is that for the 9mm to have comparable performance to 45acp is that the 9mm needs to use premium, bonded bullets. Whereas the 45 acp, you got much more leniency with your jhp ammo.
With the trend of going to smaller & trimmer 9mms result in single stack for better conceal drops in it's capacity and lighter recoil advantage.
