I have the fake 1911 in 9mm, the Star Model B Super. It has all the ergos, lack of recoil and accuracy of a 1911 9mm without the price.
I might score a Rock Island 9mm one day, but my gun money just went to buy another full size 9mm pistol with a 5"+ barrel.
This brings up another point. 9mm really benefits a 5" barrel as it is a relatively high pressure cartridge compared to 45 ACP. All these "duty size" 9mm pistols are made for LE carry convenience, but the typical 4" barrel gives up 50 fps and, therefore, muzzle energy.
