Of course, get what makes you happy! If that is the Colt, so be it!
That said, a good Model 17 is hard to beat. Ditto the 18. My experience also is that it may take 2 or 3 Model 17s to find one that is superbly accurate [e.g.: < 1" benched @25 yds]. You would spend a LOT of money trying that with Colts, as I doubt they are more accurate than the Smiths.
