There is nothing I know of, short of a custom Glock, which has the same fit, feel, and function of a Glock. Something which might work for you would be a Springfield XD or a double-stack 1911 - like the Spartan.
I can sympathize with you. I admire the mechanical and supposed functional quality of Glocks (I can't stand the way they feel in my hand, personally), but they are indeed ugly as sin. Their different angles contrast with each other, and the blockish overall shape is an eye sore. Yes, it appears to certain people (those who like "modern/cubism" design and non-organic forms), but to me it just looks like something made on the cheap with shortcuts made in appearance exclusively to save cost in manufacturing by not having to make as many cuts in the metal.
Seriously: would it have been too hard for Glock to have beveled the slide a bit more, or put a little more effort into making the contours less jarring?
Personally, I don't think this:
...would offer too much, if anything, in terms of function over this:
(Sorry for the crude photoshopping - I'm not a graphics person.)
Personally, I'm suprised Glock hasn't come out with different Glock designs - or, at least, materials. For instance, aluminum framed Glocks with different patterns on the grip (some company makes glock metal frames, in case you're interested: i imagine changing the grip pattern, etc. on those would look a bit less stupid than it does on the plastic framed ones), or even metal framed glocks with removeable wooden side panels. I suppose the Glock design doesn't allow for much modification in that department due to it's narrowly-defined dimensions, though...
I've never heard anyone describe another tool as "ugly". Are there any ugly hammers? Chainsaws? Arc-welders? Garage-door openers?
There are, though it matters less because they aren't as dependent on eye-hand coordination as a firearm is, and they're not carried daily but used relatively infrequently like a pistol is. And, generally, even hammers are fairly attractive: stainless steel, female-like contours, rounded edges... kinda like the beavertail on a 1911, actually.
