I like the 9mm better, lighter, faster pistol and less kick, barrel climbing. Cheaper ammo for lots of practice and loaded with Remington Golden Saber ammo about the same stopping power as a 45.
As far as magazine capacity, adequate to defend myself is what I want, not what some idiot politicain *feels* should be adequate.
Ever try the 10mm?
For example, the Glock 20...same size frame as Glock 21 in .45 acp, yet much less recoil, does not climb, gun pushes slightly back into your hand..with the right ammo, equivalency of a .41 magnum, very fast repeat shots.
Or get a hotter load like the Double Tap 230 grain hard cast, little more climbing than like .45acp!
Downside 10mm ammo is more expensive, less available. ;(
