I’m the same height as you and, for me at least, the 1911 Government Model grip is absolutely perfect. Frankly, it might be a matter of getting used to it.
As mentioned above, you can get thinner grips for a 1911 (though with some of these you do have to replace the screw bushings). If it’s got an arched mainspring housing, replacing it with a flat housing can also help.
Other handguns that come to mind:
Sig P239 in .40 S&W.
Walther P99 in .40 S&W (however, you may find the trigger a bit of a reach).
Glock single stack .45 ACP (I forget the model). Also, any of the Glock .40 S&W’s.
Sig P220 in .45 ACP (though I don’t think it’s any smaller than a 1911).
S&W also makes several single stack 40 S&W and .45 ACP pistols. (Though, personally, I’d take any of the above before I’d get a S&W.)
