What's the grip material on that 637? Looks nice, classy.
Here in MI I've noticed Taurus to be a great buy, particularly with certain dealers, and S&W to be much higher than what you guys are paying for a new 637. Years ago I used to see the 3rd gen autos going for MSRP, roughly the same price as comparable Sigs. The autos have no resale here though, used to see peices in exc. condition between 3-400. The wheelguns seemed to retain much more value.
Have for years thought about getting a 442 but will probably get a Taurus CIA instead one of these days(a couple other guns I want/need more), a .357 though. I liked the 905 IB I handled, just wish it came with a concealed hammer/dao lockwork in the Centennial/CIA style. One thing I always liked about Taurus as a company, was the large selection of calibers, paricularly when it came to their Ti snubs (.45 LC,.45 ACP,.41 Mag,.44 spl.,7 shot .357 in medium frame, 9mm, .40 S&W, etc.). That, and the price is right. The 85 MULTI I shot was a hell of a gun, I just prefer the high backstrap feel on the CIA (and defensive capabilities not possible with traditional handgun designs).
In your case can't think of a good reason not to get the Smith, as you will have resale value there, and a brand steeped in American history. Around here it would prolly be a price gap of 200 or even more, but if it's only 60. more it would kind of be silly to not choose the S&W, and that is to take nothing away from Taurus. To save 60. is a big deal to me and would normally be a big factor in selecting,(if I was really on the fence and would be happy with either) but look at the deal you're getting. I almost guarantee you couldn't find that revolver for under 500 in these parts.
What I'd really like is a Colt snub, either a pre-70 Dick Special or the other way and obtain a Magnum Carry, but those are just to expensive for me, and too valuable to actually use. Still my muscle memory from having an Anaconda says to open a cylinder, pull back, not push forward. Harder to get used to than it sounds.
