While I'm going to stop short of giving a recommendation, I will say that I've generally been satisfied with the entry level Smith and Wesson I bought a couple of years ago. Granted, a typical range trip for me is usually only 20-40 rounds, but I haven't had a bit of issue with mine and haven't missed the forward assist or dust cover which they deleted on the 'sport' model. For my usage, I don't have a need for anything 'better', and have been strongly considering a second as a spare.
That being said, while I have no experience with them, the most common recommendation I've seen online is that, when in doubt, its hard to go wrong with the Colt 6920 that Walmart sells. I'd probably start my research there.
