I wanted one - until last summer, when I finally shot one! Horribly inaccurate with .45 Colts - and shot swirled from it with .410 shot - all you can find locally. Plus, the only .45 Colt ammo I have found, outside of one dedicated gunstore, is the infamous 'cowboy' type (This excludes my basement 'factory'.).
Of course, I have been jaded by owning at least one .45 Colt 625MG for the last six years (Two for the last three years!). Of course, the 3" 4510 weighs less - 29 oz vs 39.5 oz, but the S&W is an N-frame - with six .45 Colt chambers vs five of the Taurus. The trigger is far better, not to mention the quality, warranty, etc. Get a 625MG and find some CCI shotshells in .45 Colt for snakes, if you must. Believe me, 250gr Speer Gold Dots - or some 255gr LSWCs - in .45 Colt will serve you better in self defense, in your home or car.
