I was wondering if anyone had any knoweldge of the 5903 and 6903 pistols? I held a 5906 and I thought it was perty heavy for carry. I will probably get a m&p for carry. I was thinking a maybe getting something for the glove box in the wifes car.
To me, the aluminum framed guns are significantly lighter. I prefer them in 9mm Smiths, but steel in my .45s. I carried a 5904 (think blued 5903) for a long time, the 5906 seems significantly heavier to me. Check the specs on them both, I can't recall how much difference there is right off hand. Given the same circumstances now, though, I'd probably carry the M&P, but I think there are some police trade-ins of the ones you mentioned floating around for 325-375.
As to whether they are "any good," I consider them to be as reliable as anything out there. I am not an expert, but my department issued 5906s for years, and I had a lot of chances, while training officers, to see them work. I have seen a few extractors break (work hardening?), an ejector, and a side plate break...out of many, many thousands of rounds I've seen fired downrange. Their only downside, for most folks, is the DA/SA system. I learned to shoot on it and don't mind it, but some do, so make sure that is acceptable to you.
If you don't get what you need here, go to the autopistol area of http://smith-wessonforum.com/eve/forums/ . You'll find a lot of experience with the 3rd generation guns there, a couple of armorers and more than a couple of knowledgeable tinkerers.
I still have the first custom gun i built, It's a 6906. It has well over 70,000 rounds through it, and it still is great. I have replaced the recoil spring twice but other than that very nice guns. It is the nicest gun that for some reason when the mag ban happened smith quit building and it would have been the best gun for the times of about anything out there. CHECK 360 David
I have a 5946 (DAO version of a 5906) that I bought just to have the DAO and it was available. It seems quite heavy, but when I put it in my 4566 holster (just to check carry/comfort) and it doesn't seem all that heavy on the belt. Of course, that was just for about an hour around the house. I actually just bought the gun for "fun" and possibly as a second HD piece. I'm very happy with it so far and don't think I'll be trading it away or selling it any time soon...or ever...
