Well, I have a Governor. Got it used from that buddy that runs the shop at a great price, which helped. I viewed it as a dead-of-night instant response weapon. The big night front is great for that. It also can be fitted with Pachmayr K/L Compac Pro's which translates into the best fit for my little paws, as my wife calls them. They're not that little...... Anyway, using Winchester PDX1 .410 loads (which is three 000 buckshot sized discs backed by twelve BB-sized pellets, at 7 yards there is a deadly 12 inch grouping of said components. It would be a fist sized clump at 10-15 feet. And in a 30 ounce gun, it is borderline harsh. Traditional .410 shotshells are mellow by comparison. The .45 Colt and ACP rounds shoot well enough, although I have a Redhawk and 2 Colt 1911's that are better platforms. And it it fitted and finished impeccably with a big ol' hammer spur to latch onto, which I wish the Redhawk had.
Had S&W been the first to introduce this type of revolver I wonder if the overall perception/reception would be better, instead of being seen by many as a gimmick attempt by Taurus to make some money.
It's not for everybody. I like others of my guns much guns better. But it's not just a fun or snake gun either, when stuffed with dedicated defense loads. Maybe some misinformed people buy it expecting to reduce bad guys to mush, knocked back 6 feet by the force of impact. Of course it won't. But it hasn't got any flies on it, either, to use one of Jack O'Connor's phrases.
