Congratulations, your ego has just been suckered by an idiot. The guy was full of it, and either didn't know what he was talking about or was trying to get you to sell it to him for a good price!
Obviously, an alloy frame will not last the same number of rounds as a steel frame. I'm sure you know that already. However, given reasonable care that frame will last at LEAST 10-15,000 rounds, which is a helluva lot of ammo to run through one pistol in your lifetime. By "reasonable" I mean not abusing it with +++P loads and cleaning and lubing it every once in awhile. If in the end you're still not convinced, e-mail me privately and we'll discuss, uh, "recouping" your expenses on that gun.
As for the hammer bite, you can either install one of the many drop-in beavertails on the market, or else just take a Gov't Model grip safety and cut a relief notch in it for the hammer.
